Breath is the vehicle of consciousness and so, by its slow measured observation and distribution, we learn to tug our attention away from external desires toward a judicious, intelligent awareness.
We must create a marriage between the awareness of the body and that of the mind. When two parties do not cooperate, there is unhappiness on both sides.
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.
