Here now they say,--All other sacrifices come to an end, but the Agnihotra does not come to an end. Although that which lasts for twelve years is indeed limited, this (Agnihotra) is nevertheless unlimited, since, when one has offered in the evening, he knows that he will offer in the morning; and when one has offered in the morning, he knows that he will again offer in the evening. Hence that Agnihotra is unlimited, and in consequence of this its unlimitedness, creatures are here born unlimited. And, verily, he who thus knows the unlimitedness of the Agnihotra, is himself born unlimited in prosperity and offspring.
