Aitareyabrahmana 5.23

5.23

Then they creep forward; they enter the sadas.
The other sacrificial priests creep out in their respective directions; the udgātṛs creep together.
They chant on the verses to the Queen of Serpents.
She indeed is the Queen of Serpents, for she is the queen of whatever creeps. In the beginning, she was hairless.
She saw this mantra:
'This spotted bull has approached.'
This variegated, manifold form entered her,
whatever desire she desired—
whatever this is: plants, trees, all forms.
Variegated, manifold form enters him, he obtains whatever desire he desires, who knows thus.
With the mind he introduces the chant, with the mind he sings, with the mind he joins in the response; with speech he recites.
Speech and mind are a copulative pair of the gods.
Through that copulative pair of the gods they secure a copulative pair;
through the copulative pair of the gods they propagate for the sake of reproduction.
He propagates with offspring and cattle, who knows thus. Then
the hotṛ priest recites the Caturhotṛs; thus he recites alongside that which was chanted.
The Caturhotṛs are indeed that sacrificial, secret name of the gods.
In that the hotṛ priest recites the Caturhotṛs,
he brings to light that sacrificial, secret name of the gods;
brought to light, it brings him to light.
He comes to light, who knows thus.
If fame should not come to a learned brāhmaṇa,
thus he used to say: going forth into the wilderness, knotting together tufts of darbha grass,
seating the brahman priest to the south, he should recite the Caturhotṛs.
The Caturhotṛs are indeed that sacrificial, secret name of the gods.
In that he should recite the Caturhotṛs,
he brings to light that sacrificial, secret name of the gods;
brought to light, it brings him to light.
He comes to light, who knows thus.
