Asana. 

If it is not devotional, it is not yoga, it is just exercise. In every posture you have a chance to experience devotion. That's what postures are really about. Worship the God in you and marvel at the beautiful engineering of your own body.

We go through another change when we take postures. A posture means you conscious of a body area. As you hold it, you become self-conscious of yourself, and if you really put yourself into it, you become a conscious self. And if you reach this awareness across many postures, you become conscious consciousness.
