'First was he founded by the founders here, the best offering priest, worthy of praise at the sacrifices; he whom Apnavâna and the Bhrigus kindled, shining brightly in the wood, and spreading from house to house:'--even as a supplicant would speak politely, 'Surely thou art the descendant of so and so! surely thou art able to do this!' so in this (verse). And what he (Agni) really is, as such he speaks of him when he says 'spreading from house to house,' for he does indeed spread from house to house.
