Angirasasmriti 2.12: dvādaśo 'dhyāyaḥ

Hereafter, I shall proclaim the auspicious rule of expiation, / having studied, heard, and remembered which, twice-born men are indeed liberated.

He should always bathe at the three ablution times; having bathed once, he should drink milk; / having bathed in the morning, he should constantly begin the muttered prayer.

He should mutter the Sāvitrī verse or the sacred utterances eight thousand times, / placing the syllable Oṃ at the beginning and in between each repeated form.

If capable, he should remain standing or in the hero's posture, or merely seated; / his seat should be piercing like a thorn; he should always sleep on the ground.

If cow's milk is unavailable, it should be cow's curd; / in the absence of curd, it should be buttermilk; in the absence of buttermilk, barley gruel.

Whichever one of these is available, he should drink that; / mixed with cow urine, the twice-born should drink that barley gruel.

This holy penance, begun with the syllable Om, / known by the name of vajra penance, was prescribed by Aṅgiras himself.

This expiation is prescribed for those joined with sins; / those involved in major sins are purified in three years.

Then minor sins must be considered, and likewise one should assign the time; / and for the time as declared, the Brahmin is the authority therein.

The Brahmins alone are the sacred field; the Brahmins alone are the deity; / by the grace of Brahmins the sun shines in heaven.

There is no field equal to a Brahmin, there is no fire equal to a Brahmin;
there is no rule higher than a Brahmin, no deity beyond a Brahmin.

Among those who whisper prayers, offer oblations, give gifts, and even among the virtuous,
the Brahmin, who is truly arisen as the field of fire, is singled out today as superior.

It is not spilled, it does not fail, it never perishes at all:
an oblation offered into the mouth of a Brahmin is superior to the Agnihotra sacrifices.

Of gods, ancestors, and living beings, a certain one belongs to a certain person,
[but] all deities reside in a Brahmin, and he is the deity of everyone.

Whatever deity one may wish to propitiate as the imperishable,
one should always please Brahmins with effort by every means.

Being the cause of attaining all prosperity, being comets to the mountain-like misfortunes that have arisen,
being the bridge over the boundless ocean of worldly existence—may the dust of Brahmins' feet purify me.

Thus ends the twelfth chapter, named "The Description of the Nature of Penances and the Rest," in the treatise on religious duty by Aṅgiras.

Thus ends the Uttarāṅgirasa.

Thus ends the Āṅgirasasmṛti.
