Prasna-Upanishad: Sixth Prapathaka

37. Therefore let a man perform all these ceremonies with the syllable Om (at the beginning). Its splendour is endless, and it is declared to be threefold, in the fire (of the altar), in the sun (the deity), in the breath (the sacrificer). Now this is the channel to increase the food, which makes what is offered in the fire ascend to the sun. The sap which flows from thence, rains down as with the sound of a hymn. 'By it there are vital breaths, from them there is offspring. And here they quote:

'The offering which is offered in the fire, goes to the sun; the sun rains it down by his rays; thus food comes, and from food the birth of living beings .'

And thus he said:

'The oblation which is properly thrown on the fire, goes toward the sun; from the sun comes rain, from rain food, from food living beings'.'

38. He who offers the Agnihotra breaks through the net of desire. Then, cutting through bewilderment, never approving of anger, meditating on one desire (that of liberty), he breaks through the shrine of Brahman with its four nets, and proceeds thence to the ether. For having there broken through the (four) spheres of the Sun, the Moon, the Fire, and Goodness, he then, being purified himself, beholds dwelling in goodness, immovable, immortal, indestructible, firm, bearing the name of Vishnu, the highest abode, endowed with love of truth and omniscience, the self-dependent Intelligence (Brahman), standing in its own greatness. And here they quote:

'In the midst of the sun stands the moon, in the midst of the moon the fire, in the midst of fire goodness, in the midst of goodness the Eternal.'

Having meditated on him who has the breadth of a thumb within the span (of the heart) in the body, who is smaller than small, he obtains the nature of the Highest; there all desires are fulfilled. And on this they quote:

'Having the breadth of a thumb within the span (of the heart) in the body, like the flame of a lamp, burning twofold or threefold, that glorified Brahman, the great God, has entered into all the worlds. Om! Adoration to Brahman! Adoration!'
