Agniveshyagrihyasutra 2.6.7

Then having performed the five sacrifices in succession beginning with the Brahma-sacrifice,

having then performed the sacrifice to the gods, and after that the sacrifice to the ancestors,

and having performed the sacrifice to beings, and the human sacrifice as well,

having thus performed the sacrifices in five ways according to the prescribed rules,

having made a circle with cow dung at the door of the house according to place,

he should properly present balls of food to an outcaste, dogs, and the like.

Having performed the worship prescribed for the gods, having smeared with cow dung a square ground measuring a cow-hide, having smeared a triangle for a Kṣatriya, and having smeared a circle for a Vaiśya, he takes his meal.

Brahmā, Viṣṇu, Rudra, Śrī, and the Fire-eater

subsist by means of the circle; therefore one should make the circle.

Sorcerers, Piśācas, Yakṣas, Rākṣasas, and Kinnaras

indeed destroy the strength of food that is devoid of a circle.

Thus [it is said].

In accordance with this statement, having diligently made a circle, having wet feet, sitting facing east, firmly placing his left foot on the ground, facing downward, restrained in speech, having touched with his left hand a vessel made of leaves or of bell-metal, he should serve cooked rice mixed with ghee, salt, condiments, and the like;

then one should eat, so they say.

The food should not be seen by a menstruating woman or the like.

At mere sight [of such a person], he should raise his right hand up to his head or up to his heart.

He sprinkles clarified butter over [the food].

Then he circum-pours water clockwise.

"I pour around you, the divine order, with truth"—[this he says] in the evening.

"I pour around you, truth, with the divine order"—[this he says] in the morning.

Having washed his hand, he touches the food with the food-hymn, with the ten-verse hymn: "I am the first-born of the divine order."

Then he sips water, saying: "You are the under-spreading of ambrosia."

Then he offers the vital-breath oblations: "Settled in prāṇa, I offer ambrosia; be auspicious to me, without burning; svāhā to prāṇa"—[thus] to prāṇa;

"Settled in apāna, I offer ambrosia; be auspicious to me, without burning; svāhā to apāna"—[thus] to apāna;

"Settled in vyāna, I offer ambrosia; be auspicious to me, without burning; svāhā to vyāna"—[thus] to vyāna.

With: "Settled in the udāna, I sacrifice immortality; auspicious, enter me, not for burning; to the udāna, svāhā!" [he offers] to the udāna.

With: "Settled in the samāna, I sacrifice immortality; auspicious, enter me, not for burning; to the samāna, svāhā!" [he offers] to the samāna.

Or [he offers] with: "To the prāṇa, svāhā! To the apāna, svāhā! To the vyāna, svāhā! To the udāna, svāhā! To the samāna, svāhā!"

Having offered these oblations, he eats as he desires. He should not bite root and fruit condiments with the tooth, [nor] any condiments [or] fatty substances raised with the foot.

There is no fault in repeated drinking.

Having offered as prescribed with curd mixed with oblation-food, threefold food, and having sipped water, having sipped water with: "You are the cover of immortality," and having sipped water again, he touches the navel region with: "You are the knot of the life-breaths; do not loosen me!"

Acting thus at every meal, he attains the fruit of fasting for a day and night.

If he wishes to sleep, he should think that there is no negligence [only when] not with head to the north, not subject to the crossbeam, not with feet toward the door, not on a parvan day, not during festivals, not on ashes, not in temples of the planets, temples of spirits, or fire sanctuaries, not naked, not impure, not at the two twilights, not on a broken bed, and not in the shadows of a cremation ground or large trees.

He should lie down with his head to the east or with his head to the south. ||7
