A lamp does not flicker in a place where no wind blows; so it is with a yogi, who controls his mind, intellect and self, being absorbed in the spirit within him.
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.
