Agniveshyagrihyasutra 2.4.6

Now we shall explain the hundredfold anointing.

If he desires [to perform the rite when] a thousand months have been completed, in his hundredth year, during the northern course of the sun, in the waxing half of the month, under an auspicious constellation, having served Brahmins with food and caused them to pronounce auspicious day, good fortune, and prosperity; then, having performed [the rites] from the drawing of lines on the sacrificial ground up to the praṇītā waters, having risen up and made a square sacrificial ground with unhusked and husked rice grains in all directions in front of the fire in each quarter, having strewn it all around with fruits, flowers, husked rice grains, unbroken grains, barley, and sesame seeds, having made two bunches of grass a span long, even, with their tips pointing east, having laid out the sacrificial ground with the bunches of grass pointing east; then, having wound thread around twenty-five pots made of gold, silver, copper, or clay, having set them on the sacrificial grounds, having strewn [grass] all around and placed a water-strainer, he brings water into the water-strainer provided with all perfumes, fruits, flowers, and sesame seeds.

Having laid down a bunch of grass, having adorned the pots with unbroken grains, perfumes, flowers, incense, lamps, and so forth, he invokes [the deities] into the pots of all the directions.

Then in the middle of this [he says]: 'I invoke Brahmā.'

'I invoke Prajāpati.'

'I invoke Parameṣṭhin.'

'I invoke Hiraṇyagarbha.'

'I invoke the Self-existent.'

Having thus invoked [them], having invoked Indra and the others into the pots in order from the east, saying 'I invoke...', having performed [the rites] from the putting on of the enclosing sticks up to the mouth of the fire, having worshiped the deity and revered it with water for arghya, pādya, and so forth according to the rule, he then bathes him.

Having sprinkled him with the three [verses beginning with] 'āpo hi ṣṭhā mayobhuvaḥ', the four [beginning with] 'hiraṇyavarṇāḥ śucayaḥ pāvakāḥ', and with this anuvāka, 'pavamānaḥ suvarjanaḥ', he propitiates [the deities] with these very names, saying 'Homage to such-a-one, homage to such-a-one.'

He should give perfume, flowers, unbroken grains, and incense, having covered him with an unwashed garment.

With the twelve pots, [he recites] the hymn to Varuṇa, the remainder [...], with the water of the Śāpadhetrī, or else with the four [verses] according to their meter beginning with 'pareparetaḥ', and with the five verses beginning with 'agnirāyuṣmān'.

Then with these he performs the consecration.

Then, having washed his hands and feet and having sipped water, he puts on an unwashed garment.

In this very manner, having anointed all his limbs upward with all perfumes combined with sandalwood and agarwood, he then causes him to look up at the sun with 'ā satyena...'.

Then he pays reverence to it with 'udūyaṃ tamasaspari', 'udutyaṃ', 'citraṃ devānām', 'taccakṣurdevahitaṃ', and 'ya udagāt'.

Having spread out an erakā mat and seated himself upon it facing east, he then offers clarified butter oblations with the six [verses beginning with] 'brahma jajñānam...'.

[The ritual] from the Sviṣṭakṛt oblation up to the gift of an excellent milch cow is established.

Then, having placed the remainder of the oblation in front of the fire on a clump of darbha grass with the two [verses] 'āyuṣṭe viśvato dadhadayamagnirvareṇyaḥ' and 'āyurdā agne', then having placed a piece of gold in the remainder of the clarified butter, he shows [him] his reflection in the remainder of the clarified butter with the four [verses] according to their meter and with half-verses beginning with 'indrāya tvā tejasvate tejasvantam'.

With 'mamāgna āyuṣe varcase kṛdhi...', he gives it to a Brahmin.

'You are life, you are full life.'

'You are all-life, you are complete life.'

With the four subsequent Brāhmaṇa passages according to their meter ending with 'yato vāso manojavāḥ', he speaks the pronouncing of blessings.

Having fed the Brahmins with threefold food and having made them pronounce blessings, [he says]: 'May the Brahmin be pleased.'

Then [...] he circumambulates the village clockwise.

Then he is carried with special coverings, attendants, fly-whisks, and palm-leaf fans. Then, having mounted a chariot with conch-shells accompanied by the sound of songs and music, he should mutter the hymn for well-being: beginning with 'svasti no 'mimītā...', ending equally with 'svasti sambādheṣvabhayaṃ no astu'.

Then he makes an offering at the door.

Then, having entered another house, having honored the Brahmins, and having made them pronounce blessings, they then say concerning the children:

'Having lived for a thousand months, a life of a thousand [months], having shown the young moon, a Brahmin with his sons and grandsons attains union and co-residence [with the gods],' so said the venerable Āgniveśya.
