The history of yogasanas as a physical, mental and spiritual culture goes back into the depths of time. It is mentioned in the oldest known literature of mankind, the Vedas, which are full of spiritual wisdom, composed by realized and enlightened rishis and sages of that time. It is believed by some that the science of yoga is much older than even the Vedas.
