This Brahman shines forth indeed when the sun is seen, and it dies when it is not seen. Its splendour goes to the moon alone, the life (prana) to the air.

This Brahman shines forth indeed when the moon is seen, and it dies when it is not seen. Its splendour goes to the lightning alone, its life (prana) to the air.

This Brahman shines forth indeed when the lightning flashes, and it dies when it flashes not. Its splendour goes to the air, and the life (prana) to the air.

Thus all these deities (i. e. fire, sun, moon, lightning), having entered the air, though dead, do not vanish; and out of the very air they rise again. So much with reference to the deities (mythological). Now then with reference to the body (physiological).

13. This Brahman shines forth indeed when one speaks with speech, and it dies when one does not speak. His splendour goes to the eye alone, the life (prana) to breath (prana).

And if two mountains, the southern and northern, were to move forward trying to crush him who knows this, they would not crush him. But those who hate him and those whom he hates, they die around him.

14. Next follows the Nihsreyasadana (the accepting of the pre-eminence of prana (breath or life) by the other gods). The deities (speech, eye, ear, mind), contending with each for who was the best, went out of this body, and the body lay without breathing, withered, like a log of wood. Then speech went into it, but speaking by speech, it lay still. Then the eye went into it, but speaking by speech, and seeing by the eye, it lay still. Then the ear went into it, but speaking by speech, seeing by the eye, hearing by the car, it lay still. Then mind went into it, but speaking by speech, seeing by the eye, hearing by the ear, thinking by the mind, it lay still. Then breath (prana, life) went into it, and thence it rose at once. All these deities, having recognised the pre-eminence in prana, and having comprehended prana alone as the conscious self (pragnatman) , went out of this body with all these (five different kinds of
