3. When it is said, that 'he made three for himself,' that means that he made mind, speech, and breath for himself. As people say, 'My mind was elsewhere, I did not see; my mind was elsewhere, I did not hear,' it is clear that a man sees with his mind and hears with his mind . Desire, representation, doubt, faith, want of faith, memory , forgetfulness, shame, reflexion, fear, all this is mind. Therefore even if a man is touched on the back, he knows it through the mind.

Whatever sound there is, that is speech. Speech indeed is intended for an end or object, it is nothing by itself.

The up-breathing, the down-breathing, the back-breathing, the out-breathing, the on-breathing, all that is breathing is breath (prana) only. Verily that Self consists of it; that Self consists of speech, mind, and breath.

4. These are the three worlds: earth is speech, sky mind, heaven breath.

5. These are the three Vedas: the Rig-veda is speech, the Yagur-veda mind, the Sama-veda breath.

6. These are the Devas, Fathers, and men: the Devas are speech, the Fathers mind, men breath.

7. These are father, mother, and child: the father is mind, the mother speech, the child breath.

8. These are what is known, what is to be known, and what is unknown.

What is known, has the form of speech, for speech is known. Speech, having become this, protects man .

9. What is to be known, has the form of mind, for mind is what is to be known. Mind, having become this, protects man.

10. What is unknown, has the form of breath, for breath is unknown. Breath, having become this, protects man .

11. Of that speech (which is the food of Pragapati) earth is the body, light the form, viz. this fire. And so far as speech extends, so far extends the earth, so far extends fire.

12. Next, of this mind heaven is the body, light the form, viz. this sun. And so far as this mind

extends, so far extends heaven, so far extends the sun. If they (fire and sun) embrace each other, then wind is born, and that is Indra, and he is without a, rival. Verily a second is a rival, and he who knows this, has no rival.

13. Next, of this breath water is the body, light the form, viz. this moon. And so far as this breath extends, so far extends water, so far extends the moon.

These are all alike, all endless. And he who worships them as finite, obtains a finite world, but he who worships them as infinite, obtains an infinite world.

14. That Pragapati is the year, and he consists of sixteen digits. The nights indeed are his fifteen digits, the fixed point his sixteenth digit. He is increased and decreased by the nights. Having on the new-moon night entered with the sixteenth part into everything that has life, he is thence born again in the morning. Therefore let no one cut off the life of any living thing on that night, not even of a lizard, in honour (pugartham) of that deity.
