Then Bālāki fell silent. Ajātaśatru said to him: ‘Is that all, Bālāki?’ ‘That is all,’ said Bālāki. Ajātaśatru said to him: ‘In vain indeed did you challenge me, saying, “Let me tell you about Brahman.”’ He said: ‘He, Bālāki, who is the maker of these persons, or whose work this is—he indeed is to be known.’ Then Bālāki, with fuel in hand, approached [him, saying:] ‘May I become your pupil.’ Ajātaśatru said to him: ‘I consider it contrary to proper order that a kṣatriya should initiate a brahmin. Come, I will make you understand.’ Taking him by the hand, he walked forth. The two came upon a sleeping person. Ajātaśatru addressed him: ‘O great one, white-robed one, king Soma!’ But he remained lying down. Then he struck him with a stick; he got up immediately. Ajātaśatru said to him: ‘Where did this person lie just now, Bālāki? Where was he just now? Whence has he now come?’ There are channels of a person named Hitā, extending from the heart to the pericardium; like a hair split a thousandfold, so subtle are they.
They abide filled with the minute fluid: brown, white, black, yellow, and red. In these he then remains when, asleep, he sees no dream whatever.
