Then let him purify the contamination of the mind by the verse Ukkhishtopahatam, &c. : 'Be it food left, or food defiled by left food, be it food given by a sinner, food coming from a dead person, or from one impure from childbirth, may the purifying power of Vasu, may Agni, and the rays of Savitri, purify it, and all my sin .'

First (before eating) he surrounds (the offered food) with water (in rincing his mouth ) . Then saying, Svaha to Prana, Svaha to Apana, Svaha to Vyana, Svaha to Samana, Svaha to Udana, he offers (the food) with five invocations (in the fire of the mouth). What is over, he eats in silence, and then he surrounds (the food) once more afterwards with water (rincing the mouth after his meal). Having washed let him, after sacrificing to himself, meditate on his Self with these two verses, Prano 'gnih and Visvo 'si, viz. 'May the Highest Self as breath, as fire (digestive heat), as consisting of the

five vital airs, having entered (the body), himself satisfied, satisfy all, he who protects all.' 'Thou art Visva (all), thou art Vaisvanara (fire), all that is born is upheld by thee; may all offerings enter into thee; creatures live where thou grantest immortality to all.' He who eats according to this rule, does not in turn become food for others.

10. There is something else to be known. There is a further modification of this Self-sacrifice (the eating), namely, the food and the eater thereof. This is the explanation. The thinking Purusha (person), when he abides within the Pradhana (nature), is the feeder who feeds on the food supplied by Prakriti (nature). The elemental Self is truly his food, his maker being Pradhana (nature ). Therefore what is composed of the three qualities (gunas) is the food, but the person within is the feeder. And for this the evidence is supplied by the senses. For animals spring from seed, and as the seed is the food, therefore it is clear that what is food is Pradhana (the seed or cause of everything). Therefore, as has been said, the Purusha (person) is the eater, Prakriti, the food; and abiding within it he feeds. All that begins with the Mahat (power of intellect) and ends with the Viseshas (elements ), being developed from the distinction of nature with its three qualities, is the sign (that there must be a Purusha, an intelligent

subject). And in this manner the way with its fourteen steps has been explained . (This is comprehended in the following verse): 'This world is indeed the food, called pleasure, pain, and error (the result of the three qualities); there is no laying hold of the taste of the seed (cause), so long as there is no development (in the shape of effect).' And in its three stages also it has the character of food, as childhood, youth, and old age; for, because these are developed, therefore there is in them the character of food .
