Garudapurana 1.128

The glorious Garuḍa Mahāpurāṇa — 128 / Brahmā said: / I will proclaim the religious observances, Vyāsa, by which Hari, who grants everything, is pleased; / for a restriction prescribed by scripture is a religious observance, and that is considered ascetic heat.

The specific rules of this religious observance are self-control and the like. / One should bathe constantly at the three junctures of the day, sleep on the ground, with senses subdued.

One should avoid speaking to women, Śūdras, and outcastes, / and one should offer oblation with the five purifying substances according to one's ability.

A virtuous person should undertake all these penances; / for the sake of preserving the hair, however, one should perform the religious observance twice over.

Bell-metal, māṣa beans, lentils, chickpeas, and koradūṣa grain,
greens, honey, and another’s food: one keeping a fast should avoid [these].

Flowers, ornaments, garments, incense, fragrant unguents,
cleaning the teeth, and collyrium: these would impair a fast.

Having used a tooth-stick and taken the five products of the cow, one should perform the observance in the morning.
From drinking water repeatedly, and from chewing betel,

A fast is impaired, [as also] from sleeping by day, gambling, and sexual intercourse.
Forbearance, truthfulness, compassion, generosity, purity, restraint of the senses,

Worship of the gods, offering into the sacred fire, contentment, and non-stealing:
this tenfold dharma is traditionally taught as common to all observances.

From the sighting of stars comes the night-fast meal; eating at night is not a night-fast meal.
One should give a pala of cow-urine, and cow-dung the size of half a thumb;

One should give seven palas of milk, and three palas of curds;
one should give one pala of ghee, and one pala of kuśa-grass water.

With the Gāyatrī, with "Gandhadvārām...", with "Āpyāyasva...", taking the curds with "Dadhikrāvṇo...",
and with "Tejo 'si..." and "Devasya tvā...", one should perform the Brahmakūrca observance.

Setting up the sacred fires, consecration, sacrifices, gifts, and observances,
Vedic observances, releasing a bull, tonsure, the girdle ceremony,

Auspicious rites, and royal consecration: one should avoid [these] during an intercalary month.
From new moon to new moon is the lunar month; but by thirty solar days is the civil month;

From the sun's ingress [into a zodiac sign] is the solar month; the sidereal month consists of twenty-seven [days].
The solar month is for marriage; the civil measure is used in sacrifice and the like.

[The combination of] the second and the third, the fourth and the fifth, the sixth and the seventh, the eighth and the ninth,
the twelfth combined with the eleventh, the fourteenth with the full moon,

And the first lunar day combined with the new moon: such harmony of lunar days brings great fruit;
the reverse of this is very dreadful and destroys merit acquired in the past.

When an ascetic practice has been undertaken, menses does not destroy a woman's observance;
she should have giving and the like performed by others, and bodily rites by herself.

If a breach of an observance occurs through anger, negligence, or greed,
one should not eat for three days, and there should be shaving of the head.

In the case of bodily incapacity, one should have a son or others perform the observance;
if a twice-born observing a vow faints, one should administer water and the like.

Thus ends the one hundred and twenty-eighth chapter, entitled "Definitions of Religious Observances," in the Ācārakāṇḍa of the first section named Pūrvakhaṇḍa of the glorious Garuḍa Purāṇa.
