Translation
The disciples of Vaiśampāyana became authorities in the Yajur Veda. They were known as the Carakas because they executed strict vows to free their guru from his sin of killing a brāhmaṇa.
Now appearance of the Taittirīya branch of the Yajur Veda is described. The derivation of the name Caraka is given. On behalf of their guru, they performed (cara) vows to destroy the effects of sin of killing a brāhmaṇa, that should have been undertaken by their guru. They were adhvaryu priests, expert in Yajur Veda.
