When the breath-link between soul and body is severed by evolutionary karma, the abrupt transition called “death” ensues; the physical cells revert to their natural powerlessness. For the Kriya Yogi, however, the breath-link is severed at will by scientific wisdom, not by the rude intrusion of karmic necessity. Through actual experience, the yogi is already aware of his essential incorporeity, and does not require the somewhat pointed hint given by Death that man is badly advised to place his reliance on a physical body.
