In plain words
Ajātaśatru said to him: "Where this person has lain, Bālāki, where he has been, and whence he has come back — the channels of the heart called Hitā stretch out from the heart to the pericardium. They are as fine as a hair split a thousandfold, and they stand there in their fineness, of a tawny colour, of white, of black, of yellow, of red. In these he then is. When a man is asleep and sees no dream, he becomes one in this breath. Then speech goes into him together with all names, the eye goes into him together with all forms, the ear goes into him together with all sounds, the mind goes into him together with all thoughts. And when he wakes, then as sparks fly out in every direction from a blazing fire, so from this self the breaths go out to their several stations, and from the breaths the gods, and from the gods the worlds. As a razor is laid within its case, or as fire is held within the fire-holder, so this self of wisdom has entered into this bodily self up to the hairs and the nails."
