Kaushitakagrihyasutra 1.5: atha pañcamaḥ khaṇḍaḥ

Taking the kuśa grass with the right hand, he grasps it with the left.

Bending his right knee, he encloses the fire with three enclosing sticks with unbroken tips,

In the west, in the south, and in the north.

Having adorned [the fire], he sprinkles water around the fire three times clockwise with two young kuśa blades with [the verse], 'The great vessel' [RV 5.83.8].

And after having sacrificed.

He throws them into the fire afterwards.

Silently, once, counter-clockwise, in an ancestral rite.

He offers the sprinkled fuel bundle into the fire with [the verse], 'Well-kindled, when the axe...' [RV 5.7.8].

With [the formula], 'You are the hand of Viṣṇu,' [he holds] the dipping spoon at its base with his right [hand].

He offers the butter libations with the dipping spoon.

With the sacrificial ladle, he cuts off [portions of] the boiled sacrificial mess twice,

Three times in the case of descendants of Jamadagni.

And when there is a boiled sacrificial mess, the under-spreading, sprinkling over, and re-sprinkling [are performed] up to [the offering to] Agni Sviṣṭakṛt.

[The offering to] Agni Sviṣṭakṛt is [cut] from the northern half.

He sprinkles [it] over twice.

He does not re-anoint [the boiled sacrificial mess].

Beginning from the north-western half of the fire, he pours an unbroken offering into the south-eastern half with [the verse], 'You, O Agni, are mindfulness' [RV 1.94.1].

Beginning from the south-western half of the fire, he pours an unbroken offering into the north-eastern half with [the verse], 'Whose are these snow-clad mountains' [RV 10.121.4].

[These are] the two clarified butter libations.

The northern butter portion belongs to Agni, the southern to Soma,

With [the verses], 'O Agni, which sacrifice...' [RV 1.1.4] and 'This sacrifice...' [RV 1.91.11],

Or with: 'To Agni, svāhā,' and 'To Soma, svāhā.'

The other offerings are made in the middle.

In butter offerings, the two butter portions and the offering to Agni Sviṣṭakṛt are not constant.

"And also in the regular oblations," says Māṇḍūkeya.

With clarified butter [he offers, reciting]: "Agni is the producer; may he give this wife to me, svāhā! Soma is rich in offspring; may he make me rich in offspring through her, svāhā! Pūṣan is rich in kinsmen; through her father, mother, and brothers, may he make me rich in kinsmen, svāhā!"

In a butter-oblation, this principal insertion place is between the great mystical utterances and the universal expiation.

In a boiled sacrificial mess, [it is] between the mystical utterances and [the offering to] Agni Sviṣṭakṛt.

Having offered the universal expiation oblations with: "The waters stretched out for me…", "Out of the darkness…", "Up this…", "The bright [face of the gods]…", "Hear this my [call], O Varuṇa…", "For this I entreat you…", "You, O Agni, [turn toward] us…", "So do you, O Agni, [be nearest] to us…", "Let that be, O Mitra and Varuṇa…", "Vaṣaṭ to you, O Viṣṇu, for the sacrifices; vaṣaṭ for the unsacrificed!", "Remedy for faulty sacrifice, atonement, remove distress, for success, for complete prosperity, to the divine bodies!", "From which, O Indra, we fear…", "You to us from behind…", "Today, today, tomorrow, tomorrow…", "May Sūrya protect us from the sky…", "Bhūr, bhuvas, svar!", and "O Agni, you are the unperishing one…"; having offered a mental oblation to Prajāpati; and having offered these four great mystical utterances—having grasped with his right hand the tips of the kuśa blades that are in his left hand, and their roots with his left hand, he anoints their tips together in the dipping spoon, their middle in the clarified butter vessel, and their roots [likewise]. But if it is in boiled sacrificial messes, [he anoints] the tips in the sacrificial ladle, the middle in the dipping spoon, and the roots in the clarified butter vessel. Having thrown them into [the fire] afterward, having put the kindling wood [on the fire] with: "You are the garment of Agni", having performed the circum-sprinkling as prescribed, having thrown the enclosing sticks into [the fire] afterward, or taking fresh praṇītā water [if it is] in the regular rite, he sprinkles the directions in turn, three times each: first towards the east, then in this manner clockwise towards each direction and upward; having poured it out towards the east or towards the north, and having touched them, he touches his vital breaths and his face. [Then takes place] the dismissal of the Brahman priest.
