Kaushitakagrihyasutra 1.10: atha daśamaḥ khaṇḍaḥ

Having entered the house, sat down behind the fire upon the skin of a bull, while she holds on to him from behind upon darbha grass, the husband offers four oblations: ‘Through Agni as god, the earth-world of worlds, the Ṛgveda of Vedas, through that I pacify you, so-and-so, svāhā! Through Vāyu as god, the atmosphere-world of worlds, the Yajurveda of Vedas, through that I pacify you, so-and-so, svāhā! Through Sūrya as god, the heaven-world of worlds, the Sāmaveda of Vedas, through that I pacify you, so-and-so, svāhā! Through Candra as god, the directions-world of worlds, the Brahmaveda of Vedas, through that I pacify you, so-and-so, svāhā!’

Or: ‘Bhūḥ! Whatever inauspicious mark you have that brings death to your husband, to your brother-in-law, or to your lover, that I make [harmless] for you, so-and-so!’

The second [oblation] is accompanied by the second great mystical utterance;

the third, by the third;

the fourth, by all [the great mystical utterances] combined.

Having wiped her two eyes with the ointment of clarified butter with ‘Of non-terrible eye…’, having touched the ends of her hair with the three verses ‘With what wonderful aid does he appear…’, having muttered the four verses ‘And those two divine physicians…’, [he pours] the remnant [of the clarified butter] on her head.

Here, some place a boy of good birth on both sides upon her lap with the verse: ‘Into your womb…’

Or indeed silently.

Having placed fruits in his joined hands, he causes [the Brahmins] to announce a propitious day,

saying: ‘Be one who gives birth to male children!’

They should remain restrained in speech until the sighting of the pole-star.

When the stars become visible, he shows her the pole-star.

He should say: ‘Be firm, to be cherished by me!’ [She should say:] ‘I see the firm one; may I obtain firmness.’

With ‘I have praised Dadhikrāvan…’ and with the triplet ‘Drink and be satisfied…’, they should eat curd-rice together.

For three nights, they should sleep on the ground and eat food free from pungent flavors and salt.

In this very way while on the journey.

He should not eat together [with her on the journey].

For a year they should not have sexual intercourse, or for twelve nights, or for six nights,

or at least for three nights.

Evening and morning they should attend to the nuptial fire with barley or with rice grains.

In the evening, with: ‘To Agni, svāhā!’

In the morning, with: ‘To Sūrya, svāhā!’

At both [times], with: ‘To Agni Sviṣṭakṛt, svāhā!’

One who desires male offspring [offers] the former [oblation] with: ‘Mitra and Varuṇa are male; both the Aśvins are male; Indra and Agni are male; may a male grow in me, svāhā!’

There is no absence from home for ten nights.
