Next Pinjula Aadarsha or Pinjulaa Mirror: By the collision of two winds giving rise to a whirlwind, and the fierce solar ray dashing against it, a lightning bolt erupts and strikes the unwary vimaana. To protect against such an event, the pinjula mirror is to be installed. An eight petalled lotus is to be made of the pinjula glass. Where the petals join, a circular dandaakaara should be made. At the back two hinged bolts should be fixed. They should be wound round by wires from the cold mirror. The back should be covered with a coir-made cloth covering. It should be fixed in the southern side of the vimaana, at an arm’s height, facing the sun. The lightning will be absorbed by the projecting rods coiled with wires from the cold aadarsha mirror, and no evil effect will occur, and the pilot can proceed in safety.

Vimanas - Mathomathis

And Naalapanchaka or Five tubes: If the smoke from the kitchen over of the vimaana spreads, it will cause discomfort for people inside. Therefore the five tubes or pipes should be inserted for the smoke to go out and the air become clear. The pipes are to be manufactured as follows. Magnetic iron, pinjula mica, ghontaara metal, dhoomapaasya metal, and tortoise shell, are to be taken in the proportion of 1, 7, 5, 5, 8, purified, filled in crucible, and melted with 100 degree heat, and when ultimately cooled, a fine metal called vaataayanee metal, or window metal will result shining like gold. With that metal 5 tubular outlets, 12 inches in diameter and 12 inches in length, should be fashioned. At one end of each of the tubes should be fixed a smoke absorbing crystal. The tubes should be inserted in the 4 sides of the vimaana, forming outlets. One tube should be fixed at the ceiling. The dhoomapa crystals will attract the smoke and pass it to the outside, and clear the vimaana of its discomfort. Hence the necessity for the naalapanchaka, or five tubes.

Then Guhaa-garbha aadarsha yantra, or hidden mine discovering mechanism: According to “Yantra Sarvasva” enemies would have placed mines and bombs underground for the destruction of the vimaana, unless they are discovered and de-fused in time there would be danger. Therefore the mine-finder yantra has to be installed in the vimaana. Says kriyaasaara, out of the 72nd type of glass, make a triangular, a circular, and a quadrangular shaped glass mirrors. These are to be fixed as follows with bolts made of pancha-dhaaraa metal in a frame made of the wood of the anjishtha tree. The circular mirror should be fixed at the bottom facing downwards. The quadrangular mirror should be fixed facing upwards. The triangular mirror should be fixed to the west of these two, with a panchamukha keelee or 5 faced hinge. From the main pivot of the quadrangular mirror to the foot of the bolt at the south-east corner of the yantra, wires made of copper, tiles, and panchaasya metal should be drawn and connect them, and then the wire ends and chumbaka crystal should be placed in the mercuric-sulphur acid vessel. Four other wires should be made to circle the triangular mirror, pass through the mirror facing upwards, and fixed to the centre of the down-ward facing mirror. Then solar rays should be let in from the western side.

A screen cloth coated with mirror-like gum should be placed opposite to the triangular mirror. Then the solar rays and electric current should be passed into the acid vessel containing the crystal. When the electrified rays from the crystal are passed on to the downward facing mirror, they will explore the ground over which the vimaana is to pass, and discover mines and bombs like mahagola and agni-garbha, which may have been inserted there and reflect their complete picture in the crystal in the acid vessel. The picture will then be projected to the screen opposite in clear detail, and by washing with chemicals present a perfect photograph of the buried mines and bombs, which could then be destroyed by due safety measures. Therefore the guhaa-garbha aadarsha yantra or mine-discovering yantra is essential for a vimaana.

Its parts are as follows: First the 72nd type of mirror, known as suranjitaadarsha. “Darpana Prakarana” says: Madder-root, live coal, ox-gall, snake-gourd, mercury, karanja or galedupia arborea, copper, 3 kinds of sharkara (sugar or sand?), borax, sulphur, chaaru or silk-cotton bark, lac, kuranga, rouhinee, iron-rust, panchaanana, liquid amber, Shiva or brionia laciniosa, vishwa, mica, paarvanija, vydoorya gem stone, in the proportion of 11, 27, 5, 7, 7, 3, 7, 5, 20, 3, 7, 3, 1, 32, 30, 38, 8, 7, 3, 9, 30, duly pulverised and filling in a beaked crucible, placed in a vaaraaha furnace, and heated to the 100th degree with the aid of the tortoise-shaped bellows. When the finely boiled liquid is poured in the cooling yantra, suranjika glass of exquisite quality will result, out of which three mirrors have to be fashioned for the guhaa-garbha-aadarsha yantra.

Aanjishtha Tree: Kriyaasaara says, “Many kinds of trees are suitable for use in making yantras. Of them all the tree called aanjishtha is the finest.” “The trees having 5 qualities are 87 in number. The best among them all is aanjishtha,” says “Udbhijya tatva saaraayanee.” Agatatvalaharee also says, the five qualities such as the capacity to capture reflections, and others, are found inherent in the Aanjishtha (or madder root) tree. Therefore out of all woods the wood of that tree is most suitable for use in this yantra. Pancha-dhaara-loha In making yantras, pivots of various metals are being used. But for use in connection with the guhaa-garbha-aadarsha, or hidden mine discovering instrument, the shankus or pivots made  f pancha-dhaaraa-loha or five alloy metal are the best. Kshvinkaa, iron-pyrites, copper, indra, and ruruka, purified, powdered, and filled in mrugendra moosha crucible and boiled to 300 degree heat with beaked bellows, will yield a 5 alloy metal, strong and heavy.

Paara-granthika acid for insertion of the crystal, is described in “Moolikaarka prakaashikaa.” Mercury, bamboo salt, Indian spikenard joint, paarvanika or clerodendrum phlomides, svarna seeds or Indian labernum seeds? or yellow thistle seeds?, and ghatotkaja or American aloe, in equal quantities, should be filled in a big bellied earthen pot, heated to yield a golden hued shining liquid, which is very useful for capturing reflections. Chumbaka crystal is the one most suited for use in capturing reflections of objects. It is manufactured as per “Manipradeepikaa,” with the following ingredients. Magnet, sand, borax, ivory, shoundika or long pepper, mercury, paarvana or clerodend rum phlomoides, copper, vermillion, iron-pyrites, grudhnika, souri or marking nut, buffalo hoop, vishwakapaala, cleaned and powdered, and filled in karpala crucible and baked in a furnace with the aid of owl-nosed bellows to 100 degrees, will yield a fine image producing crystal. Pigment for coating the screen so as to present a clear picture, is called “Roopaakarshana-niryaasa,” or image reproducing niryaasa or varnish. Out of 360 such varnishes that is the best.

Says “Niryaasa kalpa”: Moonstone, crownchaka, bamboo rice, five milks from banyan, fig, keg etc., trees, magnet, udusaara, mercury, mica, pearl, earth from ant-hill, saarasvata oil, and nakha or nail? these 16 articles to be taken in equal parts, purified, should be ground for a period of 30 days in the juice of the peacock’s egg, then mixed with bilva oil and boiled for four yaamaas or twelve hours until it becomes a perfect gum or varnish. Some call it reflector varnish. Some call it virinchi-varnish. The varnish is to be evenly spread on the special cloth called patadarpana, so that it may present as on a cinematograph screen, the pictures reflecting the location of anti-aircraft mines discovered by the roopaakarshana yantra. The production of Pata-darpana is described in “Darpana-prakarana”: Gum, cotton, pratolikaa, kuranga or pallatory root, maatanga or keg tree bark, cowries, kshoneeraka, gholikachaapa, granite sand, parotikaa, sea-foam, priyangava, ghanjhotikaa, sugar-cane, rukma or argemone mexicana, kesara or mesua ferraa gum, earthen salt, suvarchala, urugha, bydaara oil, muchukunda flour, sinjaanu, anchaalika, turmeric, kaarmuka or acacia catechu, these ingredients in the proportion of 100, 58, 25, 28, 4, 12, 5, 3, 1, 30, 10, 5, 8, 12, 3, 13, 22, 27, 28, 3, 24, 7, 3, 13, should be cleansed, powdered, filled in a vessel, and boiled in the furnace with 100 degree heat, and the unified fluid should be poured on a flat surface so as to form an even surfaced sheet. After drying, the photographic niryaasa varnish is to be used to coat this sheet, for use in the Guhaa-garbha aadarsha-yantra.

Thamo yantra or Darkness creating yantra: Vimaanaas are liable to be attacked by enemies with poison fumes of Rouhinee or krakachaarimani rays. As a protection against it the thamo yantra has to be installed in the vimaana. Out of 132 types of thamo-yantras, the 62nd variety is said to be the best for safe-guarding against poison fume and ray attacks by the enemy. Black lead, aanjanika (collyrium?), vajra-tunda are to be powdered and mixed in equal quantities, filled in fish-shaped crucible and placed in crow shaped furnace, heated to 100 degrees, and poured into the cooling receptacle will yield a fine, light, strong thamo-garbha-loha, or darkness impregnated alloy metal, useful for making Thamo-yantra. The peetha or stand is to be 3 feet wide and ½ foot high, square or round. In the centre of it is to be fixed the pivot. At its front should be placed the vessel of the acid of guggala or Indian dellium. To the west should be fixed the mirror for enhancing darkness, and in the east should be fixed the solar ray attracting tube. In the centre should be fixed the wire operating wheel, and to its south should be fixed the main operating wheel or switch.

Its working is as follows. On turning the wheel in the south east, the two faced mirror fixed to the tube will revolve and collect the solar rays. By operating the wheel in the north west, the acid in the vessel will begin functioning. By slightly moving the wheel in the south-east, the solar rays will enter the crystal in the acid vessel. By turning the wheel in the west, the darkness intensifying mirror will begin to function. By turning the central wheel the rays attracted by the mirror will reach the crystal and envelop it. Then the main wheel should be revolved with great speed, when the darkness will be produced enveloping the vimaana and making it invisible, and the efforts of the enemies to attack it with poison gas and rays will miss their target and become ineffective. This yantra should be placed in the north-west sector of the Vimaana Panchavaataskandha-Naala. Iron rust, shaarana, copper, suvarchala salt, in equal parts, to be filled in mayookha crucible, placed in jumboo-mukha furnace, and using kaakamukha bellows boiled to 102 degrees and cast in the yantra, will yield a pure, light, soft, strong, nice cool metal known as vaatadhaarana loha. 4 tubes, each 2 yards long and 1 yard high, should be prepared. Like the circular opening in the top of the vimaana two openings on each and one at the bottom should be prepared. Each tube should be inserted in the said openings. Another tube 12 feet long and 3 feet high should be fixed on the western side in the opening at the top. To each tube should be attached bellows’ mouth operated by wheels. By turning the wheels of the 5 tubes the 5 poisonous winds will be sucked in and passed into the tubes to make their exit, without causing harm to the plane.

Lohasarvasva says: There are 13 air layers known as Vrishni and others. By the force of the Panktiraadhasa Kendra, they tend to jostle each other, and generate fierce forces which will be destructive to the unwary vimana which may get involved in them. Therefore the Pancha-Vaata-Skandha-Naala Yantra is to be inserted in the back portion of the vimana; to safeguard against evil consequences. Roudree Darpana Mirror. From the south-eastern side of the earth-sun axis solar rays touch the turbulent forces in the etherial regions, and burst into flames, and vimanas which may be out on their course may be destroyed by the flames. To prevent such a happening the roudree-darpana yantra should be installed in the bottom of the vimana. Says “Yantrasarvasva”, “At the time when spring passes into summer, the forces in the junctional regions of the sky, on contact by fierce solar rays, burst into tumultuous flames, and destroy all things that pass through, Therefore the roudree darpana should be fitted in the vimana as a safe-guard against that.” According to “Darpana Prakarana,” iron rust, magnet, veera iron, borax, panchaanana metal, mica, honey, red castor bark, banyan, suryavarchula or sweet-salt, gold, alika, shaarkara or benzoin tree bark, pancha tikta or 5 sours, snake gourd, and paaduka, are to be powdered, cleaned, and in equal quantities filled in padmaasya crucible, and placed in vishvodara furnace and heated to 200 degrees. The molten liquid poured into the mould will yield excellent flame-proof roudree-darpana glass.

With this roudree-darpana glass a plank of 16 feet in dimension should be prepared. A pivot 25 inches thick should be fixed at the centre of the plank. At the edge Of the pivot, two wheels should be fixed revolving with right motion and reverse motion for expanding and contracting. A wheel equipped with rods for spokes should be fixed, the spokes being 15 inches from each other. Sheets made of roudree glass, washed with linseed, drona or lucas aspera, liquid amber, and madder root oils should be fixed to the rods with hinges. Similarly crystals made of roudree-darpana glass, with 5 facets, cleaned with the oils should be fixed at the end of the rods. Between each rod 18 leaves like lotus leaves with revolving keys should be fixed. The instrument is to be shaped like an umbrella. The leaves should be fixed at the pivot top with 8 keys. When the burning flames are imminent, the pilot should turn the expansion wheel vigorously, and the umbrella will open up and provide a shielding cover for the vimana. The lotus petals, the crystals, and the enveloping cover will protect the vimana from the threatened danger.

Next, the Vaata-skandhana-naala: According to “Gati-nirnaya-adhyaaya” In the Aavaha and other giant wind spheres there are 122 kinds of different motions of the wind. In the summer season the 79th kind of motion occurs mostly. When the vimana travels in the 4th region of the sky, it tends to zig-zag owing to the wind currents, and cause hardship to pilots and other occupants. Therefore as a safe-guard against it, the Vaatastambhana-naala-yantra should be installed in the bottom section of the vimana. Says “Yantra Sarvasva”, The vaatastambhana naala yantra should be manufactured with the vaatastambhana metal only. According to “Lohatatva prakarana,” dantee or croton seeds, suvarchala or sun-flower salt, mayoora or sulphur, lohapanchaka or copper, brass, tin, lead, and iron, bhrisundika, suranjika or sulphate of mercury, varaahaanghri loha, virohina or creya arboria, kuberaka, muraarikaanghri metal, ranjika or phosphorus, suhamsanetraka, dala or folia malabathy, courie sea-shell, mrinaalikaa or lotus stalk, to be powdered, cleaned, and in equal quantities filled in matsya or fish-shaped crucible, and placed in maaghima furnace, and with the aid of vijrimbhana bellows duly melted, will yield a molten liquid which when poured into the mould and cooled will yield an excellent vaatastambhana loha.

With that metal 6 naalas or tubes of 15 inches diameter, with wide openings should be prepared and fixed in the tail and centre and front of the vimana 10 inches deep, east to west and north to south, and held together with hoop iron binders. At the mouth of each tube a vaatapaa or air imbibing crystal should be fixed by wires. Between the tubes flags or pennants made of cotton-cloth duly processed, should be tied. And wheels made of the special metal should be fixed above each pennant. When the vaataayanee wind blast blows, the pennants will flutter noisily, and the wheels fixed underneath them will also revolve as also the crystals. The fluttering pennants pass the blowing wind to the wheels which pass them on to the crystals, which will pass them into the tubes from which they will be ejected through openings to the outside. That will protect the vimana from their interference.

Next Vidyuddarpana Yantra: Sowdaaminee kalaa explains it as follows: During the rainy season, when rain clouds gather in the sky, lightning of five kinds begin to play. They are named vaaruni, agnimukha, danda, mahat, raavanika. Of them, vaaruni and agnimukha are very active and fearful and are likely to be attracted by the roudree-darpana and other mirrors and cause fires which destroy the vimana. In order to prevent that the vidyud-yantras should be installed in the front and the right side of the aeroplane.

According to Yantra-Sarvasva: In order to protect the plane from lightning, vaaruni and agni, the vidyuddarpana should be installed in the vimana. Darpana Prakarana explains its structure: Kuranga or pallatory root, panchaasya metal, virinchi, shonaja or red lead, sand, alum, kutbha or hellebore, pearl, sundaaliga, mercury, yavakshaara or salt-petre, borax, bidouja salt, pingaaksha or terminalia chebula (?), cowries, and karbura or hedychum specatum, powdered and purified, in the proportion of 10, 7, 4, 3, 12, 2, 3, 7, 11, 27, 14, 3, 22, 18, 5, and 11, filled in padmaasya crucible, placed in vishvodara furnace, and with the aid of the 5 mouthed bellows heated to 500 degrees, the molten liquid will yield in the cooling mould a glass which is impregnated with 300 shaktis or forces, and can overpower the lightning blasts from the vaaruni and agni forces, shining with wonderful rays, and capable of spreading its own lighting force within 2 kshanas or a few seconds to a distance of 5 yojanas or 15 miles.

With that lightning darpana glass should be constructed the Vidyuddarpana yantra. A plank, 20 feet in diameter and 1 foot high, square or circular in shape should be prepared, 4 glass tubes of crescent moon shape should be fixed around the peetha or plank. In the centre should be fixed a cage made of chumbuka glass, fitted with wires and 5 faced switches at each face, and 5 goblets made of vidyuddarpana. In the centre should be fixed a spire made of the same glass with 7 cross spokes and tubes, 8 faced and 10 angled. By turning the key inside, the spire is to revolve with speed. That will attract and contain the lightning emitted by the clouds. The rays will expel it to the outer air region, and incapacitate it. Then a snow-like cool temperature will render the interior of the vimana safe and pleasant for the pilot and other occupants. Therefore this vidyuddarpana yantra should be installed duly in the vimana. Shabda-Kendra Mukha Yantra.

“Kriyaasaara”‘ says– The spots from which sounds emanate in the sky are called shabda-kendras or sound centres. The different directions from which the sounds are projected are called shabda-kendra mukhas. The yantra which is meant to control the sounds so projected is called shabda-kendra mukha yantra. Out of 304 classified sounds the sounds of water-laden clouds, wind, and lightning are said to be fiercest. In the 8th region of the sky these three sounds unify in the shishira Ritu or February-March period, and produce ear-splitting thunders. They would deafen pilots and others in the vimana. As protection against that the shabda-kendra mukha yantra is to be installed. It is said in Shabda-nibandhana, “By the combination of water, fire, air, and sky, sound is generated both among living and life-less objects. The sounds in the word “Shabdaha,” i.e., sha, b, d, and ha, indicate water, fire air, and sky symbolically.”

“Naamarthha-kalpa” says:-  Author now deals with the nature of sound or “shabdaha”. The word consisting of sounds sha, ba, da, and ha, stands for water, fire, air, and sky. By the combination of these four forces in various proportions, 304 different kinds of sounds are generated. The Braahmana bhaaga of the Veda also says shabdaas are of 304 kinds, such as sphota or embryo, very feeble sound, feeble sound, manda or soft, very soft, fast, very fast, medium, very medium, great sound, thunder sound, and thunder-bolt sound. It is said in Yantra-Sarvasva, In the 8th region of the sky, by the concatenation of water-cloud, wind and fire, an extremely fearful thunder clap will occur which will blast the ears of pilots who may enter the region. To safeguard against that the vaataskandha mukha yantra is to be installed in the vimana. In the 8th region of the sky there are 307 centres of sound. From the 70th centre a fierce sound proceeds by the force of water. From the 312th centre a fierce sound produced by wind will emanate. Similarly from the 82nd centre a fierce sound generated by lightning will emanate. By collision of the three a terrible sound will result which will deafen the pilots of the vimana. Therefore facing each sound emanation centre the shabdopasamhaara yantra is to be established.

The construction of the yantra is as follows: Gavyaarika, monkey’s skin, duck-weed, shana-kosha or jute product, crounchika or lotus stalk, vaaripishtaka or shag, roonthaaka, flesh, elephant trunk, and tin, are to be purified, and the nine elements, other than the skin, in equal parts, filled in niryaasa yantra and baked for 3 days with buffalo bile, will yield a decoction of fine scarlet colour. Seven times this decoction should be spread on the skin, and left to dry in the sun. The skin will then acquire the capacity to suppress sound. A box 2 feet long and 1 foot high made of badhira or deaf metal is to be made. Two pipes made of the same metal shaped like crane’s beak, should be fixed inside it. Above it should be fixed an umbrella made of shabdapaa darpana, or sound-drinking glass. A crystal washed with tulasee or basil seed oil should be placed inside the monkey skin and sealed with rhinoceros gum. The sealed skin with crystal should be placed in the central pipe inside the box. Monkey skin alone should be placed in the pipe on the left side. Thin wires should connect them all and be fitted with hinges and switches. Above the canopy of the box a monkey skin shaped like lion’s mouth should be connected by wire through a pipe to the crystal in the tube inside the box. The top of the box should be covered, securely.

Badhira loha or deaf-proof metal is explained in Lohatantra-Prakarana; lime fruit, laguda or sweet-scented oleander, virinchi, rishika or water-calteop, maaloora or Bengal quince, panchaanana metal, luntaaka, varasimhika or solenum xunthokurpum, kuravaka or gigantic swallow-wort, sarpaasya or mesua ferrea, vaakula or surinam medlar, jack-fruit, camphor and vatika or salvinia cusullata, in equal parts, purified, and filled in tryutee crucible, and heated in the furnace, will when cast produce a metal, cold, dark, sound-proof, powerful, able to control bleeding, and draw out missile parts from the war wounds of soldiers and healing them, and capable of reducing the effect of thunder claps. The simhaasya bellows is to collect the fierce sound and transmit it to the crystal inside the metal box so that the monkey skin will absorb it and stifle its intensity. Therefore shabda-kendra mukha yantra should be installed in the vimana.

Vidyud-dwaadashaka Yantra, or Yantra of 12 lightnings is explained in Kriyaasaara. In the realm of the comets and shooting stars in the sky, at the 8th region there are 30703221 shooting stars. 8000 of them are prone to lightnings, and 12 of them known as mahaakaala etc., are of importance. Shakti-tantra says, “The 12 lightnings which form the eyes of the shooting stars are named, rochishee, daahakaa, simhee, patanga, kaalanemikaa, lataa, vrindaa, rataa, chandee, mahormee, paarvanee, mridaa.”

Kheta-sarvasva Says: Mahaakaala, mahaagraasa, mahaajwaalaamukha, visphulinga mukha, deerghavaala, khanja, mahormika, sphulinga-vamana, ganda, deergha-jihva, duronaka, and sarpaasya are 12 comets with 12 lightning eyes. The lightning effects of the comets are extremely severe in the period of sharat or autumn, October and November, and vasanta or spring, March and April. By the collision of the solar rays and the lightnings a force called ajagara is created. When the vimana reaches the 20th region of the sky, that force paralyses the plane. To protect against such happenings the vidyuddwaadasha yantra is to be installed.

Yantra Sarvasva also Says: Vidyuddwaadasa yantra is excellent in protecting against the lightning effect of comets. Its details are as follow. First duly coated jataghana should be prepared. It should have 22 folds so as to cover the vimana. Poundraka and other crystals should be fixed in each of the folds. Then mahorna acid should be placed inside in the north-east side of the vimana. 8 rods, each of 6 arms length, made of anti-lightning glass should be fixed in the 8 directions over the cover of the vimana. At the beginning, middle, and end of the vimana canopy, spring wheels made of dambholee metal, 5 faced and interconnected should be fixed with revolving bolts. Cages made of wire should enclose the poundraka crystals, and the wire terminals should be attached to the spring wheels. The wire ends from 4 of the cages should have a common switch. On the main wheel being put in speedy motion the 12 crystal cages will revolve, the enveloping cloth cover will spread out, and the lightning absorbing power of the cloth will be activated. The crystals will attract the ajagara lightning, bifurcate the comet lightning from the solar rays, and transmit it to the 8 rods. The rods will absorb and then transfer the lightning power to the folds of the power proof cloth. By operating the central switch in the enclosure, a force called vidyut-kuthaarika, or lightning-axe, will be generated in the acid, and it will attract the comet force from the cloth, and submerge it in the acid. Then by operating the end switch in the enclosure, the ajagara force in the acid will dart towards the pataghana cloth-cover and take refuge, where upon the blowing wind will evaporate it and nullify its effects, and the vimana will be out of danger.

According to Darpana Prakarana:- Shundaala metal, mridakaantaka or mountain ebony, ghanodara, budilaakara or tamarind, vatsanaabha poison, pankaja or eclipta prostrala, kutilaraga, naga or mesua ferrea, white sand, vara or syndhava salt, garada, mica, garala, or honey product, mukha, shringa, sphatika crystal, avara, muktaaphala or pearl? guggulu or boswellia glabra, kaanta or steel, kuranja or Indian beach, natron, salt-petre, borax, copper, snake scale, udupa, barren tree, sonamukhee or Tinnevelly senna, brown barked acacia, jaambalika or citrus grass lemongrass? kusha grass, kudmala or flower bud, gold, these 26 ingredients, purified and filled in crucible and placed in padmaakara furnace, and with the aid of simhaasya or lion-faced bellows heated to 300 degrees, and poured into the mould, will yield a fine anti-lightning glass.

Dambhola loha or thunderbolt metal is thus described in Lohatatitra-Prakarana: Urvaaraka, kaaravika, kuranga, shundaalika, chandramukha, virancha, kraantodara, yaalika, simhavaktra, jyotsnaakara, kshwinka, pancha-mourtwika, metals should be purified and placed in mandooka-or frog-crucible, placed in the five faced furnace, and with the aid panchamukha or 5 mouthed bellows heated to 500 degrees, will yield the dambholi alloy. Poundrika crystals are described in Maniprakarana which describes the poundrika crystal. Poundrika, jrimbhaka, shibira, apalochana, chapalaghna, amshupamani, veeragha, gajatundika, taaraa mukha, maandalika, panchaasya, amrita sechaka, these 12 crystals are destroyers of ajigara. Draavaka prakarana explains mahorna acid: pynaaka, panchamukha, ammonium chloride, wild liquorice, iron-pyrites, kudupa, vajrakanda, budila, mercury, steel, charcoal, mica, these in equal parts purified and boiled in acid boiler, will yield mahorna acid.

Praana-Kundalinee Yantra: According to “Kheta-Sarvasva,” where the contact of smoke, lightning and wind courses in the sky occurs is the praanakundalee position. The yantra which can control, restrain, and set in motion the forces of these three in their several courses, is called praana-kundalee yantra. According to Kriyaasaara, the yantra which is installed in the praanakundalee kendra of the vimana in order to control the forces of lightning, wind, and smoke, and adjusts their movements is called praana-kundalinee yantra. Says Yantra-sarvasva, “In order to control the movements of the forces of smoke, electricity and wind, and make them disperse, move, halt, or make stunt move or reverse move, the praana-kundalinee yantra is installed in the vimana. A peetha or stand 3 feet in diametre and 3 feet high, square or. circular, should be made of vrishala metal, with 8 kendras or central spots. In each central spot, two wheels with revolving hinges; small peethaas or plates with 3 holes, 4 teeth, 3 pivots, in their middle a central pivot, three red-coloured tubes or pipes with opening and closing wheels, and switches for right motion, and reverse motion, with a shabda-naala in the centre, with wheels (with hinges and rods) which will flap the wings; from the north-east and south-east kendras and the middle-kendra in the west up to the middle of the course of the yaana kundalinee revolving wheels with pivots. Motions are by means of hand wheels. By the operation of the several wheels the plane will be set in motion. From the central pivot of the 8 kendras strong wires should pass the eastern peetha or footboard through randhras or holes and reach the tops of the 3 tubes at the window. The 3 forces should be made to aid the motion of the vimana, and the remnant of the force should be passed through the 8 tubes and get lost in the sky, leaving the vimana unperturbed.”

Shaktyudgama Yantra:- The eight powers of the planets and stars, at the time of full moon in the month of kaartika,–i.e., November-December, are pulled forcefully by mahaa-vaarunee shakti or great cold force. In the 137th route in the sky there is a jala-pinjooshikaa shakti which will attract and spread them all over, and there will be a fierce outburst of dew and snow. Then 3 currents will be generated: one will be a damp cold air flow; the second will be a wet dewy flow; and the third will be a cold air flow. When the vimana approaches that region, the first force will divest it of all power. The second force will benumb the pilots and operators. The third force will envelop the vimana and make it invisible. Thus overcome, the vimana will crash. As protection against such a happening the shaktyudgama yantra should be fixed in the navel spot of the vimana.

“Khetasangraha” says:- “Eight planets are, Mars, Sun, Saturn, Venus, Mercury, Moon, Jupiter, and Ruru. And krittikaa, shatabhisha, makha, mrigashiras, chitra, shravana, pushya, and ashvinee are eight luminous stars. In the course of their transit through space the planets and stars approach each other in the period of sharat or autumn generating eight forces.” “Chaaranibandhana” also says, “According to the science of astronomy, planets and stars in the course of their perambulations happen to approach one-another. Then conflict arises between the magnetic and electric forces of planet and star, and eight cold forces are generated in consequence.”

“Shakti-sarvasva” says, “When the star krittika comes near planet Mars, a force called shaktyudgamaa is generated. Similarly, by the star shatabhisha coming near the planet, Sun, a cold force called jwaalaamukhee is generated. By the nearness of mrigashiraa and Venus a damp cold windy force called mahojjwalaa is generated. By the approach of star makhaa to planet Saturn a force called shytya-damshtraa is generated. By the approach of chitta to Mercury a force called shytya-hymaa is generated. By the approach of shravana to Moon a cold wave force called sphoranee is generated. By the nearness of pushya to Ruru a force called mahormilaa in generated. And by the approach of ashwinee towards Jupiter a force called mandookinee is generated.

These eight forces, shytyodgamaa, sheeta jwaalaa-mukhee, shytya-damshtraa, sheetarasa-jwaalaa, shytya hemaa, sphoranee, sheetarasa-ghanaatmikaa, and shytya-mandookinee, by mutual inter-play according to the seasons, will become six new forces.” Says “Ritukalpa,”–“In spring the differing forces will be 5, in summer 7. in the rainy season 8, in autumn 3, in hemanta or cold season 10, and in winter 2. The 3 forces during autumn are as follows. The planet-star forces by contact with the sun’s rays, assume 3 forms. Sheeta-jwaala, shytya-damshtraa, and shytyodgamaa, coalesce and become sheetarasa-vaata shakti. Shytya-rasa-jwaalaa, shytya hymaa, and sphoranee coalesce and become vaari sheetasheekaraa shakti. Shytya-ghanarasaa and shytya mandookinee become sheeta-vaata-rasa-praavaahika shakti.”

Yantra Sarvasva Says:-  “To protect the vimana from the effects of these three forces the shaktyudgama yantra should be installed. First with the shytyagraahaka loha or cold-absorbing metal, protective hoods should be prepared both for the pilot and for the plane. At the front and tail portion of the aeroplane cover should be fitted switches for contraction and expansion. In the front or elbow hinge of the supporting beam of the covers the two sandhi-keelie should be fitted. Three tubes should be prepared out of the cold-proof glass, and should be fitted in front and on either side of the pilot’s cock-pit. Bhraamanee chakra or wheel should be fitted at the front. When the three shaktis or forces attack the vimana, the expansion wheel should be revolved vigorously. It will first cover the pilots and then cover the entire plane also. By operating the bhraamanee wheel the attacking forces will be slowly absorbed, and the shaktis will be forced through the cold air tubes. By operating the main switch of the naala tantries, or wires, the forces will be made to go through the tubes into the outside air, and vanish therein. The pilot and the vimana will both be saved from danger.

“Loha-tantra” describes the shytya-graahaka loha, or cold absorbing metal as follows: Blue lotus, crowdika or rhinoceros horn or vaaraahi root, somakanda, vishwaavasu, crownchika alloy, chandrakaanta or moon-stone, vaardhyashvaka alloy, varuna tree, 5 kudmalas, simhaasya, shankhalavaa, and goose-berry, to be purified and in equal quantities filled in shundaalaka crucible, placed in chanchoomukha kunda, and with panchaanana bellows heated will yield a fine cold-capturing alloy. “Darpana prakarana” describes cold-proof glass: lead, kapaalee, moonstone, castor, margosa seed, trinaanga or cus-cus grass, kshaara-traya or natron, salt-petre, and borax, suvarchalaa or sun-flower?, fine sand, bhaarika, collyrium or eye-black, kuranga or pallatory root, panchormikaa, chandrarasa, and shivarika, purified and in equal quantities filled in simhika crucible, placed in padmaakara furnace, and with the aid of shoorpodara bellows heated to 300 degrees, and poured into mould and cooled, will yield an excellent sheetaghna darpana or cold-proof glass.

Vakra-prasaarana Yantra: Enemies attempt to destroy one’s vimana by missiles and dambholi and other mechanisms. The pilot should discover them by means of mukura and other yantras and immediately change course and avoid the trouble. Therefore the Vakraprasaarana yantra, or diversion enabling mechanism should be installed in the vimana.

Yantra Sarvasva says:- “When there is danger from dambholi and 8 other kinds of destructive mechanisms contrived by enemies, in order to escape that danger the vakraprasaarana yantra is prescribed: Sulphate of iron, sacred peepul gum, and copper 16 parts, krishnaaguru or black sandalwood 3 parts, zinc 5 parts, collyrium 1 part, should be purified and mixed and boiled with 100 degree heat. Aaraara copper alloy will be formed, goldish and light and hard. A wheel 3 feet wide and 3 feet high should be made out of it. It should have a pivot, and be installed in the bottom of the eeshaadanda axle moola of the vimana. Four inches thick and of arm’s length, with 16 wheels having band-saw toothed edges attached to two pivots, oil-cleaned, with 3 joints, with oil-cleaned rods attached to the saw-toothed wheels, with keys; in the middle should be fixed 2 keys which will eject smoke, and 2 keys which will shut off smoke. Proper wiring should connect the several parts. This will enable the vimana to zigzag like a serpent, to reverse, and to divert so as to avoid the danger zone, and get out safely.”
