Thereupon Balaki was silent. To him then Ajatasatru said: So much only Balaki? 'So much only' replied Balaki. To him, then, Ajatasatru said: In vain, indeed, did you make to converse saying 'Let me declare Brahman to you'. He, indeed. Balaki, who is the maker of these persons, of whom verily this is the work, he alone is to be known. Thereupon Balaki, fuel in hand, approached saying, 'Receive me as a pupil'. To him then Ajatasatru said: 'This I deem a form (of conduct) contrary to nature that a Kshatriya should receive a Brahmana as pupil. (But come). I shall make you understand'. Then taking him by the hand, he went forth. The two then came upon a person asleep. The Ajatasatru called him (saying) 'O Great, White-robed King, Soma!' But he just lay silent. Then he pushed him with a stick. He got up at once. To him then Ajatasatru said: Where in this case, O Balaki, has this person lain? What has become of him here? Whence has he returned here? Thereupon Balaki understood not. To him then Ajatasatru said: Where in this case, O Balaki has this person lain, what has become of him here, whence he has returned here as I asked is the arteries of a person (of the heart) called Hita (the beneficent). From the heart they spread forth to the pericardium. Now they are as minute as a hair divided a thousand-fold. They consist of a minute essence, reddish-brown, white, black, yellow and red. In these one remains while asleep; he sees no dream whatsoever.
