Through the mystic yoga practice called pranayama, the yogi controls the airs within the body to maintain the body in a healthy condition. In this way, the yogi comes to the point of trance and tries to see the Supersoul within the core of his heart. Pranayama is the means to attain samadhi, trance, in order to fully absorb oneself in seeing the Supreme Lord as antaryami, the Supersoul within the core of the heart.
