Part 3- Vyana Vata

Vata is concerned with gati- motor and gandhana- sensory functions of the body. The life of an individual is dependent upon these two functions. The movements may be visible or invisible. Both pranavata and udanavata are concerned with some of these visible and invisible movements in the body. The locomotion is a visible movement and it is one of the most important functions of a living being. All movements are effected through the contractions and relaxations of the muscles. The vyanavata is the next sub-division which is in control of the voluntary movement of the body.
Location of vyana vata-
No specific place as location of vyana has been mentioned by charaka and susruta, but both agreed that it pervades swiftly through the body. According to vagbhata the vyana is located in hrdaya, but traversed through out the body very swiltly.
Function of vyana vata-
According to charaka the functions of vyana vata are motion (gati), extension (prasarana), withdrawal (akshepa), blinking of eyes (Nimesha), etc and proper ejection of rasadhatu into the circulation throughout the body. According to susruta, the function are-

  1. Effective transport, circulation of rasa- rasadhatu or aahararasa in the body.
  2. Out flow of blood and sweat from the body.
  3. Five kinds of movements viz. extension (prasarna), contraction (akunchana), bending (vinamana), upward movement (unnamana), and lateral movement (tiryaggamana).
  4. The movement described by both charaka and susruta are voluntary in nature and pertain to the locomotion of the body. In ashtangasangraha, vagbhata added the yawning, recognizing the taste of food, cleansing the channels, effecting the outflow of the sweat and blood from the body, depositing the semen inside the vaginal cavity, separating the essence of the food from the waste matter and nourshing the dhatus. These functions are also due either directly or indirectly to the voluntary movements of the body. In Ashtangahridaya, Vagbhata concised all function of vyanavata by the statement that all action or movements of the body are conducted by it.
