The word asana literally means a posture. Out of the innumerable asanas a body can assume, 84 have been identified as Yogasanas, through which one can transform the body and mind into a possibility for ultimate well-being.
Yogasanas are not exercises, but rather very subtle processes to manipulate one’s energy in a particular direction.
Treat yoga as your healthy doctor who lets you know what is wrong inside you. From feelings or pride, ego, and fear to physical disorders, yoga examines you totally. The postures in yogasana help you to become strong and flexible so that no negative thought or issue can bother you further.
