Jaiminīya (Talavakāra) Brāhmaṇa 58.319

58.319

Ten are the fingers of the hands; ten are the toes of the feet; seven are the breaths in the head.
That makes twenty-seven.
The fifth day is twenty-sevenfold.
Thereby it is corresponded to.
Ten are the fingers of the hands; ten are the toes of the feet; ten are the breaths; mind, speech, and heart [make three].
That makes thirty-three.
The sixth day is thirty-threefold.
Thereby it is corresponded to.
The breaths are the seventh day, which is related to the Gāyatrī.
The eye is the eighth day, which is related to the Triṣṭubh.
The ear is the ninth day, which is related to the Jagatī.
Speech is the tenth day, which is related to the Anuṣṭubh.
Now, what is above the two ears, that is the subsequent Atirātra.
The in-breath is the prior Atirātra; the out-breath is the subsequent.
They call them cryptically the introductory and concluding [rites].
He is established in the in-breath and down-breath; he does not falter through the in-breath and down-breath; he attains a full lifespan.
Thus indeed the entire twelve-day rite corresponds to the self; all desires accrue to him who knows thus.
