Garudapurana 1.121

The glorious Garuḍa Mahāpurāṇa — 121 / Brahmā said: / I declare the four-month observances; one should undertake them on the eleventh day, / or on the full-moon day of Āṣāḍha, having worshipped Hari with everything:

‘This religious observance, O God, has been undertaken by me in your presence; / let it reach completion without obstacles, with you being pleased, O Keśava!

If I should die while this religious observance is undertaken and incomplete, O God, / then let it become complete for me by your grace, O Janārdana!’

Having worshipped thus, one should undertake the observance's worship, recitation, and the like; / and all sin goes to destruction for one who wishes to perform Hari's religious observance.

Whoever, having bathed and worshipped, undertakes the observance's worship, recitation, and the like, / and, having bathed, worships Viṣṇu for the four months eating once a day, / he goes to Viṣṇu's world, which is free of all stain.

One who abstains from intoxicating drink, meat, and liquor becomes knowledgeable in the Vedas from worshipping Hari; / one who abstains from oil attains Viṣṇu's world; one who performs a quarter-kṛcchra shares in Viṣṇu.

From fasting for one single night, one becomes a celestial traveling in an aerial chariot; / from three nights, a man goes to Śvetadvīpa; one who eats only at the sixth mealtime [reaches the same].

From the cāndrāyaṇa penance, one attains Hari's abode and unasked liberation; / the prājāpatya penance brings Viṣṇu's world; the performer of the parāka observance attains Hari.

Eating barley meal, barley gruel, or alms; consuming milk, curds, and ghee; / taking cow urine and barley as food; eating the five products of the cow; / eating vegetables, roots, fruits, and the like, and abstaining from spiced juices, one shares in Viṣṇu.

Thus ends the one hundred and twenty-first chapter, entitled “Explanation of the Four-Month Religious Observance,” in the section on conduct, within the first portion of the first section in the glorious and great Garuḍa Purāṇa.
