Agniveshyagrihyasutra 2.6.5

Having offered the Vaiśvadeva offering, he should wait for guests for the duration of milking a cow.

A learned Vedic scholar, one observing Vedic vows, an ascetic, one constant in duty, or one of equal conduct [may be the guest].

For him [who omits the daily rites], an offering to Manasvat is prescribed as an expiation.

When [the offerings] have been interrupted for two or three days, and when they are omitted through negligence,

Having offered three offerings accompanied by Tantumat verses, he should sacrifice with four Vāruṇa verses.

When they have been completely interrupted for ten or twelve days, however,

Having offered four offerings accompanied by Abhyāvartin verses, a sacrificial cooked offering to Tantumat is to be prepared.

In whose house a woman or an uninitiated boy presents the food offering to the fire,

There the Kūṣmāṇḍa verses should be offered by him; having made the offering, [it is] for the prosperity of the sacrifice.

For one setting out on a journey in whose house no performer is found,

He departs along with these five great sacrifices,

And he performs them on the journey with whatever food is obtained.

If food is not obtained, he should enter into them with water;

He should perform the observance with water alone, following the vow according to what is available.

By the sacrifice to the gods, the twice-born reaches equality with the gods;

By the sacrifice to the ancestors, [equality] with the ancestors; by the sacrifices of offerings to beings, with the beings;

By the sacrifice to men, [equality] with Manu; by the Brahma-sacrifice, with Brahman.

Having attained equality with these deities for a hundred years,

They go to Brahman, which is bliss, fixed, eternal, and imperishable.

Thus [it is said].

Now, [if] a guest comes to him—one of conduct equal to his teacher, a forest hermit, or a bath-graduate, or a righteous king—

Having risen to meet them, he offers a seat, water for the feet, an offering of hospitality, [and] water for the guest-reception.

Whatever food grains are there should be given.

Or he may perform another hospitality procedure.

However, the distribution of food grains is to be done by one possessing wealth.

In the absence [of food]: "Ground, water, grass, and pleasant speech—these indeed never run out in the house of a virtuous man." Thus [it is said].

These [practices], they say, are the highest Brahman.

At their reception, one should observe a vow for twelve nights: eating food without pungent spices or salt, sleeping on the ground, and chastity.

Having fasted for three nights, he should take the other two offerings.

The bali-offering has been explained. ||5
