The word asana literally means a posture. Yogasanas are offered as a set of powerful postures to transform the body and the mind into a possibility for ultimate well-being. They are not taught merely for physical fitness and strength, but are a way of aligning the inner system to the celestial geometry, becoming in sync with the existence, thereby naturally achieving a state of health, joy and bliss. Out of the innumerable asanas a body can assume, 84 have been identified as Yogasanas.
