Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
But it is I who am the ritual, I the sacriﬁce, the offering to the ancestors, the healing herb, the transcendental chant. I am the butter and the ﬁre and the offering.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The Vedic sacriﬁce known as Jyotistoma is also Krsna, and He is also the Maha-yajna mentioned in the smrti. The oblations offered to the Pitrloka or the sacriﬁce performed to please the Pitrloka, considered as a kind of drug in the form of clariﬁed butter, is also Krsna. The mantras chanted in this connection are also Krsna. And many other commodities made with milk products for offering in the sacriﬁces are also Krsna. The ﬁre is also Krsna because ﬁre is one of the ﬁve material elements and is therefore claimed as the separated energy of Krsna. In other words, the Vedic sacriﬁces recommended in the karma-kanda division of the Vedas are in total also Krsna. Or, in other words, those who are engaged in rendering devotional service unto Krsna are to be understood to have performed all the sacriﬁces recommended in the Vedas.
