Jaiminīya (Talavakāra) Brāhmaṇa 58.349

With the mind he took hold of their speech. That same speech, even today, is seized by the mind; for whatever one desires in mind, that one speaks with speech. He considered: 'In what form, indeed, might I take their speech?' He made the form of a man. In the form of a man he took their speech. Therefore, a man speaks all forms of speech. Having gathered these waters, he ascended upwards. He went to where there is this world of food called the Bull. For the bull is indeed food; when one eats, then he acts like a bull. He considered: 'What form, indeed, might I assume that another would not ascend to me?' He became a dappled goat. Therefore, we do not come upon a dappled goat. Then those waters which he carried away, which are these waters above—they are these very ones. And that speech which he carried away, which is this thunder above—it is that very speech. And that which flashes within the waters, he looked down upon these creatures who were hungry,

babbling in blind darkness.

Cutting off a single syllable of this speech, he emitted it as: 'Vāc!'

Having fallen, it came to rest in the midst of these worlds.

That became this disk [of the sun].

He breathed after it.

That became the breath.

It dawned for them.

Yet being hungry, he dripped a single drop of these waters: 'How much indeed will be sufficient for them?'

[thinking].

It became tenfold, hundredfold, thousandfold; it became as large as this earth.

Approaching it, they churned it.

It became a churned potion.

That is the churned potion's nature as a churned potion.

Having eaten it, they breathed upward.
