Garudapurana 2.37

Venerable Garuḍa Mahāpurāṇa — 37
Tārkṣya said:
Declare to me accurately the gift of the water-jar;
by what rite must this action be performed, O Janārdana?

What are their characteristics? With what are they filled? To whom are they to be given, O Janārdana?
At what time should they be presented, accomplishing the satisfaction of the pretas?

The Holy Kṛṣṇa said:
I will declare again truly the gift of the water-jar.
They should be given dedicated to the preta, accompanied by food and water;
especially, O Great Bird, they bestow liberation upon the preta.

On the twelfth day, at six months, at three fortnights, or at the year,
water-jars should be given for his comfort on the journey.

Day by day, water-jars accompanied by sesame seeds should be given
on a well-smeared piece of ground, filled with cooked food and water.

A vessel should be given there for the preta according to wish;
well pleased by that gift, the preta departs with the messengers of Yama.

On the twelfth day in particular, one should cause water-jars to be given,
having made the intention there according to rule for twelve jars.

One water-pitcher there, filled with cooked food and fruits,
should be given dedicated to Viṣṇu, having vowed it to an auspicious Brahmin.

One [jar] indeed to Dharmarāja; when he is pleased, one attains liberation;
and one to Citragupta; gone there, one will be happy.

The sixteen and other [jars] should be given, filled with bean food and water.

Beginning with the funeral rite at departure up to the sixteen śrāddhas,
one should offer [a jar] to each of sixteen Brahmins.

Beginning from the eleventh day, daily should be given [a jar] named Dṛḍha,
filled with cooked food and water, every day until the end of a year.

Large water-vessels and jars are given,
and one water-pitcher there; upon it a vessel made of bamboo.

One should cover it with a cloth, having worshipped it with fragrant scents;
one should cause them to be given filled with water, especially to Brahmins.

Having made the intention day after day according to rule, O King of Birds,
[it should be given] to a noble Brahmin endowed with Vedic conduct,

It should be given to one endowed with learning and conduct, never to a fool;
one rich in Vedic conduct is capable both of delivering [others] and crossing over [himself].

Thus in the venerable Garuḍa Mahāpurāṇa, in the second part, in the Pretakalpa, in the Dharmakāṇḍa, the thirty-seventh chapter, named "Ascertainment of the Śrāddha with Water-jars."
