9. Therefore, verily, he who knows this has both these [i. e. breath and the sun] as his soul (ātman, self); he (Ātman), meditates only in himself, he sacrifices only in himself. Such meditation and a mind devoted to such practise—that is a thing praised by the wise.

One should purify the impurity of his mind with [the

formula] ‘What has been touched by leavings.’ He repeats the formula (mantra):—

‘Leavings and what has been touched by leavings,
And what has been given by a bad man, or [what is impure]
because of a still-birth—
Let the cleansing power of Vasu, Agni, and the rays of Savitṛi
Purify my food and any other thing that may be evil!’

First [i. e. before eating] he swathes [his breath] with water. ‘Hail to the Prāṇa breath! Hail to the Apāna breath! Hail to the Vyāna breath! Hail to the Samāna breath! Hail to the Udāna breath!’—with these five Hails he offers the oblation.

Then, with voice restrained, he eats the remainder.

Then, afterwards, he again swathes with water.

So, having sipped, having made the sacrifice to the Soul, he should meditate upon the Soul with the two [formulas] ‘As breath and fire’ and ‘Thou’rt all’:—

‘As breath and fire, the highest Soul (Ātman)
Has entered in with the five winds.
May He, when pleased himself, please all—
The all-enjoyer!’

‘Thou’rt all, the Universal art!
By thee is everything that’s born supported;
And into thee let all oblations enter!
There creatures live, where thou art, All-immortal!’

So he who eats by this rule, indeed, comes not again into the condition of food.
