Others perform the sacrifice of wealth, the sacrifice of penance, the sacrifice of concentration of mind, the sacrifice of Vedic study, and of knowledge, and others are ascetics of rigid vows. Some offer up the upward life-breath into the downward life-breath, and the downward life-breath into the upper life-breath, and stopping up the motions of the upward and downward life-breaths, devote themselves to the restraint of the life-breaths. Others, who (take) limited food, offer up the life-breaths into the life-breaths. All of these, conversant with the sacrifice, have their sins destroyed by the sacrifice. Those who eat the nectar-like leavings of the sacrifice repair to the eternal Brahman.
