Agatasatru said to him: 'Do not challenge me on this. I meditate on him as death. Whoso meditates on him thus, neither he himself nor his offspring will die before the time.'

15. Balaki said: 'The person that is embodied, on him I meditate.'

Agatasatru said to him: 'Do not challenge me on this. I meditate on him as Lord of creatures. Whose, meditates on him thus, is multiplied in offspring and cattle.'

16. Balaki said: 'The Self which is conscious (pragna), and by whom he who sleeps here, walks about in sleep, on him I meditate.'

Agatasatru said to him: 'Do not challenge me on this. I meditate on him as Yama the king. Whoso meditates on him thus, everything is subdued for his excellencies.'

17. Balaki said: 'The person that is in the right eye, on him I meditate.'

Agatasatru said to him: 'Do not challenge me on this. I meditate on him as the self of the name, as the self of fire, as the self of splendour. Whoso meditates on him thus, he becomes the self of these.'

18. Balaki said The person that is in the left eye, on him I meditate.'

Agatasatru said to him: 'Do not challenge me on this. I meditate on him as the self of the true, as the self of lightning, as the self of light. Whoso

meditates on him thus, he becomes the self of these.'

19. After this Balaki became silent. Agatasatru said to him: 'Thus far only (do you know), O Balaki?' 'Thus far only,' replied Balaki.

Then Agatasatru said to him: 'Vainly did you challenge me, saying: 'Shall I tell you Brahman? O Balaki, he who is the maker of those persons (whom you mentioned), he of whom all this is the work, he alone is to be known.'

Thereupon Balaki came, carrying fuel in his hand, saying: 'May I come to you as a pupil?' Agatasatru said to him: 'I deem it improper that a Kshatriya should initiate a Brahmana. Come, I shall make you know clearly.' Then taking him by the hand, he went forth. And the two together came to a person who was asleep. And Agatasatru called him, saying: 'Thou great one, clad in white raiment, Soma, King .' But he remained lying. Then he pushed him with a stick, and he rose at once. Then said Agatasatru to him: 'Balaki, where did this person here sleep? Where was he? Whence came he thus back?' Balaki did not know.

20. And Agatasatru said to him: 'Where this person here slept, where he was, whence he thus came back, is this: The arteries of the heart called Hita extend from the heart of the person towards the surrounding body. Small as a hair divided a thousand times, they stand full of a thin fluid of various colours, white, black, yellow, red. In these the person is when sleeping he sees no dream.
