Agniveshyagrihyasutra 2.7.9

Now therefore domestic expiations are handed down by tradition; we shall explain them.

The remaining [expiations] belong to the solemn ritual.

"Whatever is the rule for an āhitāgni, that is the rule; whatever is the world of an āhitāgni, that is [the world] of one who maintains the domestic fire"—so says the Śāṭyāyana Brāhmaṇa.

There, whatever are sacrificial cakes [in the solemn ritual], those are boiled rice oblations here [in the domestic ritual].

The preparation of milk, curd, and speckled butter is like that of clarified butter; there is no setting upon the fire, replacement, or separate serving of curd; having performed acts directed to Agni, Rudra, the Rākṣasas, the ancestors, or Nirṛti, and cutting, breaking, discarding, and touching oneself, one should touch water.

Everywhere, in the case of spilling, breaking, scorching, burning, inversion, and omission, one should offer the two Mindā oblations with: "Yan me ātmano mindābhūt …" and "Punar agniś cakṣur adāt …".

In the case of spilling, having addressed what has spilled with "Saṃ tvā siñcāmi …", having removed [the spilled matter], having poured water over it, having stood paying reverence with "Bhūḥ", one should offer two oblations with "Askān dyauḥ pṛthivīm …".

If it is clarified butter, having also addressed it with "Devāñjana vanaspate māṃhasaḥ …", one should also give something [as a gift].

Now, in the case of breaking, having addressed what is broken with "Bhūmir bhūmnā …", having removed [the fragments], having poured water over [the spot] with "Unnambhaya pṛthivīm …", one should offer with this [verse]: "Trayastriṃśat tantavaḥ …".

One should throw wooden ones into the fire.

Now, in the case of scorching, having addressed what is burnt with "Nirṛtyai tvā …", having cast away a little toward the south-west or north-west direction with "Tvaṃ parācī tvam avācī tvaṃ rakṣāṃsi gaccha", one should offer three oblations of clarified butter with "Agnī rakṣāṃsi sedhati …".

If a portion of what approached the oblations [is burnt], having taken it out and prepared it, one should offer with this [verse].

By this, undercooked and badly cooked [oblations] are explained.

He should throw [it] into the water.

Having addressed the uncooked [offering] with: 'To Rudra thee,' and the badly cooked with: 'To Yama thee,' then, if the strewn grass burns, having addressed [the fire] with: 'Homage to the consuming Agni, homage; O consuming one, do not harm me, do not harm my house, do not harm my wealth, do not harm my cattle,' he should offer with: 'To the consuming Agni, svāhā.'

Having strewn around again with: 'Indra from all sides around you…,' he should offer with: 'To Indra, svāhā.'

Now, if an enclosing stick burns, [he addresses it] with: 'Homage to the burning Agni, homage to the burning one.'

From here on it is the same. [With the words:] 'Agni's kindling stick art thou,' [he lays] the western half; [with:] 'Yama's kindling stick art thou,' the southern half; [with:] 'Soma's kindling stick art thou,' the northern half.

He should offer two oblations with: 'Kindling thee for a hundred [winters] indeed may I…'

When [a stick] has been accepted, he should lay around another [enclosing stick], each to its respective mantra: 'A Gandharva art thou.'

Now, in case of an inverted order, he should offer four oblations with: 'O Agni, thou to us…,' 'So thou to us, O Agni…,' 'Thou, O Agni, art Ayās…,' and 'O Prajāpati…'

These same [mantras are used] if [a rite] has been omitted, with 'May Mind [and] Light…' as the fifth, and he should perform the omitted [rite].

If [the sacrifice] is completed, he should also give something [as a gift].

If, when the subsequent time has arrived, the offering of the prior [time] has not been concluded, that is a lapse of time. As an expiation for that, he should offer [the offering] of the prior [time] with: 'May Mind [and] Light…'

In like manner he should offer [the offering] of the subsequent [time].

In this way, for each offering up to ten nights, [there is] breath control.

Beginning from the eleventh up to twenty nights, [there is] fasting; beyond thirty nights, the Prājāpatya penance is prescribed.

Or, beginning from the eleventh, [he offers] three Tantumatī verses; if it has been interrupted for twelve days, the fire is to be re-established—such is said; or [it is done] thus:

Now, if a new- or full-moon day has passed, having offered four oblations with: 'May Mind [and] Light…,' 'And art thou, O Agni, Ayās…,' 'Whatever in this…,' and 'May Indra grant us welfare…,' he should prepare a cooked-food offering to Agni Pathikṛt before the eighth [day].

Beyond that, [it] is to be performed accompanied by fasting: two [oblations] when two [parvans have passed], and three when three. In this way, when they have passed, the expiation is an offering like that of the parvan. When the Ancestor-sacrifice has passed, fasting is also to be performed in both fortnights; this is established.

Now, in the case of the great sacrifices: on one day with 'May Mind [and] Light…'; on two, three, four, or five; or beginning from six, having offered three Tantumatī verses, he should mutter the four Vāruṇī verses: 'This my [call], O Varuṇa…,' 'That I ask of thee…,' 'Whatever [sin]…,' and 'Loosen up thy wrath…,' up to nine nights.

Beyond that, up to ten nights, he should offer four Abhyāvartinī verses.

In all cases, finally [an offering] is made with the mystic utterances; this is established.
