Do not think of yourself as a small, compressed, suffering thing. Think of yourself as graceful and expanding, no matter how unlikely it may seem at the time.
You have to create love and affection for your body, for what it can do for you. Love must be incarnated in the smallest pore of the skin, the smallest cell of the body to make them intelligent so they can collaborate with all the other ones, in the big republic of the body. This love must radiate from you to others.
First yoga deals with health, strength and conquest of the body. Next, it lifts the veil of difference between the body and the mind. Lastly, it leads the Sadhaka to peace and unalloyed purity.
The Yogi conquers the body by the practice of asanas, making the body a fit vehicle for the spirit. The Yogi knows that it is a necessary vehicle for the spirit, for a soul without a body is like a bird deprived of its power to fly.
While doing the postures, your mind should be in half-consciousn ess, which does not mean sleep. It means silence, emptiness, space, which can then be filled with an acute awareness of the sensations given by the posture. You watch yourself from inside. It is a full silence.
