Varahashrautasutra 2.2.3

Standing in front facing west, proceeding through the subsequent turns, he sprinkles [the altar] with ghee, with ‘May the Vasus protect you with the Rudras from behind’.

[With] ‘May Nitāna the Māruta protect you with the Maruts from the north’, ‘May the Ādityas protect you with the All-Gods from the east’, ‘May the fathers, having Yama as king, protect you with the ancestors from the south’, ‘May the divine indras, having Indra as senior, having Varuṇa as king, protect you from below and from above’—[with this last formula] in the middle.

Having addressed [them] with ‘May these bricks be milch cows for me, O Agni’, having made groats of gavīdhukā with goat's milk and dividing it into six parts, standing facing north, not overstepping the fire, he offers the Śatarudriya on the north-western brick with an arka leaf, knee-high, with [the section] beginning with ‘Homage to your wrath, O Rudra’ and ending with ‘Homage to the armies and homage to you commanders of armies’.

Navel-high, with [the section] beginning with ‘Homage to the charioteers’ and ending with ‘Homage to him of the sacred rite and him of the lightning’.

Chin-high, the third [offering] up to the descents, with [the section] beginning with ‘Homage to him of the rain and him of the drought’.

[He offers] the three descents with ‘Homage be to the Rudras who are in heaven’.

He has the sacrificer recite [the formulas] starting from the chin-high level; he offers at those spots.

He throws the arka leaf in a frequented place; ‘he should throw it in the frequented path of cattle of someone he hates’, as explained in the Brāhmaṇa.

On that very brick, he places a caru of gavīdhukā boiled in milk, with ‘Whatever Rudra is in the waters, in the fire, who is in the plants, whatever Rudra has entered all beings, to that divine Rudra be homage’.

He gives an unasked bow with three arrows to a brahmin.

Having sprinkled the fire thrice with a water pitcher with ‘Strength in the stone’, he walks around [it] thrice in reverse.

‘If he should practice sorcery, this very yajus [is used]’, as explained in the Brāhmaṇa.

On an Āgneyī-pāvamānī [verse], he sings the Gāyatra sāman; at the head, the Rathantara; on the right wing, the Bṛhat; on the left wing, the Vāmadevya; on the right hip; on the tail, the Yajñāyajñīya; Prajāpati's heart [is sung] without a verse on the wing.

They praise the arka [fire altar] with arka sāmans.

The hotṛ recites after [the sāman] has been sung.

He has the sacrificer recite the samiṣṭayajus of the fire altar, with ‘Offered is the sacrifice by the Bhṛgus’.

Having tied an avakā plant, a reed branch, [and] a frog to a bamboo pole, he drags them around the fire with the seven [formulas beginning with] ‘Thee with the ocean's avakā’.

Breath is in the frog.

Gathering up the dragging implement, he deposits it on the rubbish heap.

Having put on shoes of black antelope skin, he ascends with ‘Homage to your heat’.

Having thrown five gold chips into clarified butter taken five times, he libates across the naturally perforated [brick] five times diagonally, with the turns [ending with] ‘vaṭ to the one seated in the tree’.

With the two [remaining formulas], the last [libation] in the middle.

With curd mixed with honey, he sprinkles the fire with a large handful of darbha grass, saying: 'O lord of food...'

With the words, 'Bestower of breath,' he descends.

Having concluded up to the sprinkling, in the highest [layer], with the Pravargya-announcing group [of verses], in the western half, [he places] the fourth [brick] with 'Like this...', the fifth with 'Of such appearance...', the sixth with 'Indra, the divine clans...', [and] the seventh.

If he wishes, 'May I strike the nobility with the commoners,' it is explained in the Brāhmaṇa.

Thus ends the third section in the second chapter on the piling of the fire altar.
