Agniveshyagrihyasutra 1.2.2

The conclusion of study [takes place] under the constellation Rohiṇī in the fortnight of the Taiṣī [month], or on the full-moon day.

Having gone out together with their group towards the eastern or northern direction to where the waters are pleasant and pleasant to bathe in, having bathed in them and performed three breath controls with the Aghamarṣaṇa hymn, they sprinkle themselves with hands holding strainers, reciting the three verses, 'Waters are indeed refreshing,' the four verses, 'Golden-hued, pure, purifying,' and with the section, 'Pavamāna, the cleanser of the heavenly realm.'

Having bathed, they hand darbha grass to one another as if wishing to give to one another.

Then, on a clean, level place sloping towards the east, they arrange seats ending in the north with darbha blades whose tips point to the east,

for the groups of deities: to Brahman, to Prajāpati, to Agni, to Vāyu, to Soma, to Sūrya, to Candramas, to the constellations, to King Indra, to King Yama, to King Varuṇa, to King Soma, to King Vaiśravaṇa, to the Vasus, to the Rudras, to the Ādityas, to the All-gods, to the Sādhyas, to the Ṛbhus, to the Bhṛgus, to the Maruts, to the Atharvans, to the Aṅgirases.

Viśvāmitra, Jamadagni, Bharadvāja, Gautama, Atri, Vasiṣṭha, and Kaśyapa: these are the seven seers.

Wearing the sacred thread around the neck, to the north, on [ground] sloping to the north, they arrange seats ending in the east with darbha blades whose tips point to the north, for Viśvāmitra, Jamadagni, Bharadvāja, Gautama, Atri, Vasiṣṭha, and Kaśyapa.

Between Vasiṣṭha and Kaśyapa, they arrange [a seat] for Arundhatī.

To the south, at the edge of the single altar, they arrange [a seat] for Agastya.

To the north, [they arrange seats] for Kṛṣṇadvaipāyana, Jatukarṇa, Tarukṣa, Tṛṇabindu, Varmin, Varūthin, Vājin, Śravas, Satraśravas, Suśravas, Stutaśravas, Somaśuṣmāyaṇa, Sanatvāna, Bṛhaduktha, Vāmadeva, Vājarājña, Haritarājña, Udamāya, Gautama, Ṛṇaṃjaya, Ṛtaṃjaya, Kṛtaṃjaya, Dhanaṃjaya, Satyaṃjaya, Babhru, Trivarṇa, Trivarṣa, Tridhātu, Parāśara, Viṣṇu, Rudra, Skanda, the Lord of Kāśī, Jara, Dharma, Artha, Kāma, Krodha, Vasiṣṭha, Indra, Tvaṣṭṛ, the Creator, the Sustainer, the Ordainer, the Disposer, Death, Savitṛ, Sāvitrī, the Ṛgveda, the Yajurveda, the Sāmaveda, the Atharvaveda, and the Itihāsas and Purāṇas.

To the south, wearing the sacred thread over the right shoulder, on [ground] sloping to the south, they arrange seats ending in the west with darbha blades whose tips point to the south,

for Vaiśampāyana, Phaliṅgu, Tittiri, Ukhya, Ātreya the author of the Pada-text, Kauṇḍinya the author of the commentary, the authors of the Sūtras, Satyāṣāḍha, the authors of the expositions, the teachers, the seers, the forest-dwellers, the celibates of drawn-up seed, and the wives devoted to one husband.

Each for his own fathers, grandfathers, mothers, paternal grandmothers, paternal great-grandmothers, maternal grandfathers, maternal great-grandfathers, maternal great-great-grandfathers, maternal grandmothers, maternal great-grandmothers, maternal great-great-grandmothers, [he offers]: 'I arrange [a seat] for so-and-so, I arrange [a seat] for so-and-so, I arrange [a seat] for so-and-so' with a seat; 'I gratify so-and-so, I gratify so-and-so' with water; 'Homage to so-and-so, homage to so-and-so' with perfumes, flowers, incense, and lamps; 'To so-and-so, svāhā! To so-and-so, svāhā!' with food; 'I gratify so-and-so, I gratify so-and-so, I gratify so-and-so' with fruit-water; 'Homage to so-and-so, homage to so-and-so, homage to so-and-so'—having thus worshipped, having prepared a sacrificial ground to the west of the altar, having established the fire, and having performed [the rites] up to the mystic utterances, he makes offerings to the five section-seers.

Or having offered [with] the names of the kāṇḍas, [or to] Sāvitrī, the Ṛgveda, the Yajurveda, the Sāmaveda, the Atharvaveda, and Sadasaspati, he recites the first and last anuvākas, or the beginnings of all the kāṇḍas.

He undertakes [the offerings] beginning with the Jayas.

Having offered up to the Sviṣṭakṛt, having waited for three days or one day, they say: 'One should study according to the lesson.'

With the two [verses beginning with] 'Growing up from every knot' (kāṇḍāt kāṇḍāt prarohantī), he should plant dūrvā grass at the water's edge.

Having made waves in the water-reservoir, they run a race toward the east or north until they are exhausted.

Having returned, they gratify Brahmins with cakes, barley groats, and boiled rice.

Thus, at the conclusion of the complete recitation of the Veda, up to the planting of dūrvā grass beginning from the kāṇḍa, excluding the running into the water-reservoir, they regularly gratify the gods, the sages, and the ancestors with water—gratify them.
