'The Hotri, in the Hotri's seat, the knowing,'--the Hotri, doubtless, is Agni; the Hotri's seat is the black antelope skin; and the knowing means the wise one;--'the impetuous and glowing one, of great power, hath sat down,'--that is, the impetuous and shining one, of great power, has sat down;--'the guardian of undisturbed rites, the most wealthy,'--for he indeed is the guardian of undisturbed rites, and the most wealthy;--'the bearer of thousands, the brilliant-tongued Agni,'--a thousand means all, thus, 'the all-bearer, the brilliant-tongued Agni.' With two Trishtubh (verses) relating to Agni (he performs): the meaning of this has been told.
