Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Therefore, day by day, one who is actually aware of religious principles and is not heinously envious of poor animals should happily perform daily sacrifices and those for certain occasions with whatever food is available easily by the grace of the Lord.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The word dharmavit, meaning “one who knows the actual purpose of religion,” is very significant. As explained in Bhagavad-gita (18.66), sarva-dharman parityajya mam ekam saranam vraja: becoming Krsna conscious is the topmost stage in understanding of religious principles. One who reaches this stage performs the arcana process in devotional service. Anyone, whether a grhastha or a sannyasi, can keep small Deities of the Lord suitably packed or, if possible, installed, and thus worship the Deities of Radha-Krsna, Sita-Rama, Laksmi-Narayana, Lord Jagannatha or Sri Caitanya Mahaprabhu by offering food prepared in ghee and then offering the sanctified prasada to the forefathers, demigods and other living entities as a matter of routine daily work. All the centers of our Krsna consciousness movement have Deity worship programs very nicely going on in which food is offered to the Deity and distributed to the first-class brahmanas and Vaisnavas and even to the people in general. This performance of sacrifice brings complete satisfaction. The members of the Krsna consciousness movement engage daily in such transcendental activities. Thus in our Krsna consciousness movement there is no question at all of killing animals.
