Agniveshyagrihyasutra 3.5.8

Now, if they are not going to spread out the accompanying cow, he should set her free,

or he should give her to Brahmins.

It is known [from tradition]: "Having given [her] right here, they become [destined] for superior welfare."

Now, if he is going to release her, he leads her around counter-clockwise with the three verses: "We saw the young woman approaching…"; having led her around three times, he recites over her as she stands to the north with this [verse]: "Those who are living and those who are dead…"

Then, having plucked hairs from her ears, he should place them in the two hands only, with: "For Śyāma and Śabala, thee!"

The right on the right, the left on the left.

Then he releases her: "The mother of the Rudras, the daughter of the Vasus, the sister of the Ādityas, the navel of immortality;

I declare to the discerning person: do not slay the sinless cow Aditi!

Let her drink water! Let her eat grasses!

Om, set her free!"

Then he sets fire to him: from the east with the Āhavanīya fire, from the south with the Anvāhāryapacana fire, from the west with the Gārhapatya fire, from the north with the Sabhya and Āvasathya fires.

Here too there are portents:

If the Āhavanīya fire should blaze up against him first, one should know of him: "He has won the world of the gods."

Now if the Anvāhāryapacana fire [blazes first, he has won] the world of the ancestors.

Now if the Gārhapatya fire [blazes first, he has won] the heavenly world.

Now if the Sabhya and Āvasathya fires [blaze first, he has won] the world of the Seven Seers.

Now if all of them blaze up together, one should know of him: "He has won the world of Brahman."

And whatever the women say here, they do that.
