There is the ether within the heart, and in it there is the Person (purusha) consisting of mind, immortal, golden. Between the two palates there hangs the uvula, like a nipple—that is the starting-point of Indra (the lord). Where the root of the hair divides, there he opens the two sides of the head, and saying Bhu, he enters Agni (the fire); saying Bhuvas, he enters Vayu (air);

In plain words: Inside the heart there is a small space, and in it lives a Person made of mind who is shining, golden and cannot die. The soft flap at the back of the throat is called the starting point of Indra, the lord. Where the hair parts on the head, he opens the two sides of the head and, saying the sacred word Bhu, enters fire, and saying Bhuvas, enters the air.
