Rasa Dhatu provides Prinana (nourishment) to the body and remains in continuous circulation throughout the system. The chief tool for this action is heart. Vayu plays the most important role in the circulation of blood and other liquids of the body. Vata has been divided into five, out of these Vyana Vata is located in the heart, moves all over the body at an enormous speed with performing all activities related with the body. It has been described as highly powerful and highly speedy in the movement. Kapha and Pitta cannot move without any external power, are moved and circulated with the help of Vata.1 Gayadasa has explained Rasa Samvahana (circulation of Rasa Dhatu), Bhavamishra has added the word Adi(etc.) Though the text describes only Rasa Samvahana but the word Adi should be noted here and circulation of blood etc should be included. Sushruta outlined five different Vata acts, from which Purana (filling) should be interpreted as swallowing food, filling the stomach, and so on, as well as filling vessels like arteries and so on to maintain proper pressure.2 The heart's conduction system, the vasomotor nervous system and the contraction and relaxation of muscle tissues can all be regarded as Vyana's apparatus. Though their dispersed appearance prevents us from conducting a thorough exploration, there are sufficient findings to establish the involvement of Vyana in Rasa-Rakta Samvahana. The goal of this article is to compile and reorganize the information for proper comprehension.
