The term Dhatu Samyata is regarded as health (Arogyata) as described in Charaka Samhita. Commonly the term Dhatu is applied for Sapta Dhatus i.e. Rasa Dhatu, Rakta Dhatu etc. Dhatu term has broad meaning. The term has been clarified with respect to the concept of Dhatu and Dhatu Samyata. Acharya Charak has described that Dhatu term is applied in various meanings i.e. Chetana Dhatu, Shat Dhatu, ChaturvimshatiDhatu and Prakriti Cha Astdhatuki and Panchamhabuta are also considered as Dhatu. Here all components or factors which are responsible for sustenance of body to continue the life are considered as Dhatus. The term Dhatu Samyata has a meaning of total health and primary stage of absolute health keeping both views of existing and beyond life which is the aim of Ayurveda. Commonly Ayurveda is regarded as a medical System which has bi-dimensional aim i.e. prevention of health and cure of diseases from beginning to till now, Ayurveda is standing on some of its own principles and theories. “Dhatusamyata” theory is one of them. In current days “Dhatu Samyata” term is applied in meaning of Dosha Samyata, from applied and clinical point of view. Both terms have one approach i.e. to prevent the health and cure diseases.

Dhatu Samyata is regarded as health (Arogyata) described by Charaka, but Vagbhatta has told that Dosha Samyata is Arogyata. Dhatu term has been applied in sense of the content which sustains the physical body anatomically that is Ras Dhatu, Rakta Dhatu, Mamsa Dhatu etc. are seven Dhatus and the biological unit Vata, Pitta and Kapha which are known as Dosha. These Doshas are also regarded as Dhatu up to some extent when they are biologically functioning normally but the Dhatu term is commonly applied in sense of Sapta Dhatu. Author in his presentation discussion will be mainly oriented towards Dhatu Samayata. The right meaning of state of equilibrium etc. will be discussed on the basis of materials from different Ayurvedic classic and it will be clarified that which term is better for health, whether Dhatu Samyata or Dosha Samyata? The aim of the study/article is to clarify the basic understanding of dhatu samyata which is used in different location. So that it may help the Ayurvedic physician to take proper care of patient. It is thus necessary to highlight concept of dhatu samyata. Ayurveda stands on some own principles. According to Ayurveda body is composed of Dosha, Dhatu and Malas.

Mathomathis - Ayurveda

In reference of Dhatu samyata commonly Dosha samyata is considered. According to Vagbhatta doshas in normal state are also considered as Dhatu and is it is considered as Dosha according to its Pathogenic nature, when it is accumulated then presentation in clinical form of different diseases are known as Malas. In reference of structural Sapta dhatu and in sense of functional Dhatu, Tridosa has been considered. Normally “dhatu Samyata” is clinically assessed by clinical features where as its parametric measurement can be assessed by quantitative measures i.e. pramana of different dhatus. Since Ayurveda is based on Dravya, Guna, Karma and thus through the available content of its guna and karma, a way to understand Dhatu Samyata based on the dimension has been presented through this table.

Arogyata- A state of dhatu samyata:- DhatuSamyata is applied for Arogyata or normal health, it is stated that there is only one aim of Ayurveda which is DhatuSamyata. Dhatusamyata is regarded as karya, repeated in CharakVimanasthana in reference of parikshyabhava, DhatuSamyata is indicated as Karya and Arogyata. Specific characteristicsof Dhatusamyata are also described .

Characteristic to identify (Equilibrium of dhatu) dhatu samyata:- Equilibrium state of Dhatus means that the body is in healthy state, it is free from all the diseases and all the anatomical structure are in normal state to performed all the body functions.

Commonly dhatu term is applied for sapta dhatus but in reference of dhatu samyata all meaning of dhatus are applied. In Ayurveda “prakritichaastadhatuki” is also considered i.e. avyakta etc are also considered as dhatus along with ekdhatuki, sadadhatuki and chaturvinshati dhatuki purusha. Tridosha is also regarded as dhatu in reference of dhatusamayata. Commonly tridoshas are considered from health point of view. In current days two terms are popular in reference of health i.e. “dhatussamyata” and “doshasamyata”. Dhatu samyata theory is considered in Charaka samhita and Dosha samyata by Vagbhatta. Charaka has stated “vikarodhatuvaisamyam” in his view which is the subject of discussion. Commonly Ayurvedic persons considered such meaning of dosha and dhatusamyata, but in Charak Samhita dhatu Samyata term is applied on maximum level in reference of Karya. It has been clearly stated karya is dhatu samyata which is regarded as arogyata (health). The aims of chikista is dhatu samyata. The two types of dhatu are responsible to sustain the body, first is functional dhatus that is vata, pitta and kapha and second is structural dhatu which are sapta dhatus. Commonly kaya chikitsa is related with doshic theory and aim of chikista is based on equilibrium state or normal state of tridosha.Rasayana therapy is based on structural dhatus rasa, rakta etc.

Here dhatu samyata term includes both theories of functional and structural dhatu. The clinical bases of dhatus samyata are tridosha theory because imbalanced state of tridosha is the main cause of pathological state of dhatus. If doshas get aggravated means in forms of dosha, there is a requirement of shamana chikista while whenever there is accumulation as malas a specific shodhana therapy is applied i.e vasti chikista for vata dosha, vamana chikista for kapha dosha and virechan chikista for pitta dosha .If structural dhatus rasa, rakta etc gets decreased then there is a requirement of specific therapy known as Rasayana therapy. Here in reference of rasa, rakta dhatus etc, dhatu samyata is also applied. The primary contents of structural dhatus are Panchmahabhuta. Here accurate position in specific Dhatus is required because Karma Purusha or Sada Dhatus Purusha in composed by PanchaMahabhuta. Ayurveda has an aim to achieve the Sukha in existing life and beyond life. Moksha is the state of Sukha beyond life. The concept of Chaturvinshati Dhatu is related to birth-death, happiness-misery, rebirth-salvation etc. Among twenty four, first eight contents are also regarded as Dhatus and a normal state of those Dhatus (Dhatu Samyata) is essential. The root cause of Pravritti is described related to this Ahankara Buddhi etc are also regarded as Dhatu and its normal state is essential for normal life. The pathological states are caused by not only Tridosha directly but Pragyaparadha is also a cause to aggravate the Tridosha and it is well known that Buddhi is considered as a Dhatu in Charak Samhita.

AUTHOR CONCLUSION:- Dhatu Samyata term is more suitable term for Arogyata mentioned in Charaka Samhita. This term convinces a sound health in existing life and beyond life keeping all meaning in mind the Dhatu term has all and multidimensional scope covering all aspect of Ayurveda.
