Yoga is that which gives you pleasure and comfort.
The definition for ‘asana‘ is a posture that is stable and pleasant. You should feel comfortable when doing yoga asanas. What is the definition of comfort? When you don’t feel the body. If you are sitting in some odd positions then you feel those parts of the body, painfully. Your focus is more on the discomfort there. When you do any asana, what you feel first is discomfort. But if you take your mind through it, you will find that in just a few minutes the discomfort has disappeared and you don’t feel the body. You feel an expansion or infinity in the postures.
