Agniveshyagrihyasutra 3.4.4

Then for him the Adhvaryu kindles the Āhavanīya fire in the south-east direction, the Anvāhāryapacana in the south-west, the Gārhapatya in the north-west, and the Sabhya and Āvasathya in the north.

He should burn [the pyre] with the collections [of formulas]: "Agni with the Yajus formulas," "With the wives," and "The army of Indra."

The attendance [is performed] with the Graha formulas: "O lord of speech, arrange the name," "O lord of speech, through the vigor of speech," "Soma of Soma," "O lord of speech, with uninjured speech," and "O lord of speech, the name placed in the heart," with the seasonal formula "vāgghotā", and with "The Brahmin is the single Hotṛ."

According to some, the potsherd is in the Āhavanīya fire.

The Vājasaneyins prescribe [burning] with the Santapana fire.

He faces it, [saying]: "Whom the hot fire carries away, to which destination the valiant in battle go, free of sins, free of dust, free of grief, to that destination go, fragrant on the back of the firmament; svadhā, homage!"

If he has not maintained the sacred fires, [he follows the corpse with the formula]: 'The course which heroic warriors reach in battle, yielding their bodies, wise ones knowing liberation, virtuous doers fixed upon the sacrificial oblation of the Agnihotra—unto that course go, fragrant one, to the vault of heaven, svadhā, namaḥ!'

Then, wearing the sacred thread, having performed the pacification rite with [the formula], 'I sprinkle you with the yajus verse,' he waits upon the sun with the Jyotiṣmatī verse: 'Looking up beyond the darkness,' 'The radiant front of the gods has arisen' [and] 'Auspicious.'

The sons, brothers, and sapiṇḍa kinsmen assemble together.

Without looking back, they come to a sacred spot [at the water].

A royal officer or a person not of the same gotra stops them with a palāśa branch, a śamī branch, or an udumbara branch, saying, 'Do not cross!'

Saying, 'We will not return [to this state],' having made signs of distress, having dishevelled their hair, having cast dust [upon themselves], wearing a single garment or wearing unwashed garments, facing the south, plunging once into the water, emerging, placing the left knee upon the ground, wringing out the garment, standing up, taking water with cupped hands, [they offer] the water mixed with sesame seeds toward him, [saying], 'O so-and-so, this is your water.' Having done so a second and a third time, then without looking back they come to the village.

The youngest going first, they proceed like ants.

At the entrance of the dwelling, having chewed a neem leaf, having sipped water, having touched cow dung, gold, water, fire, mustard seeds, and sesame oil, having touched the head and the vital breaths, having stepped upon a millstone, having entered the house, they do whatever the women say.

Where the vital breaths departed, having smeared that place with cow dung, having set down a calf, having scattered sesame and rice grains mixed with water, having performed purification [with the formula], 'May there be welfare; let auspiciousness abide in what remains of the households,' eating uncooked food, [abstaining] from women, from that time onward [there is] chastity for ten nights.

In the evening and in the morning, having poured out water once, on the tenth day having poured out water thrice, on the tenth [day] he eats altered food. ||4
