SB 5.26.25

TRANSLATION
A person who in this life is proud of his eminent position and who heedlessly sacrifices animals simply for material prestige is put into the hell called Visasana after death. There the assistants of Yamaraja kill him after giving him unlimited pain.

PURPORT
In Bhagavad-gita (6.41) Krsna says, sucinam srimatam gehe yoga-bhrasto ‘bhijayate: “Because of his previous connection with bhakti-yoga, a man is born into a prestigious family of brahmanas or aristocrats.” Having taken such a birth, one should utilize it to perfect bhakti-yoga. However, due to bad association one often forgets that his prestigious position has been given to him by the Supreme Personality of Godhead, and he misuses it by performing various kinds of so-called yajnas like kali-puja or durga-puja in which poor animals are sacrificed. How such a person is punished is described herein. The word dambha-yajnesu in this verse is significant. If one violates the Vedic instructions while performing yajna and simply makes a show of sacrifice for the purpose of killing animals, he is punishable after death. In Calcutta there are many slaughterhouses where animal flesh is sold that has supposedly been offered in sacrifice before the goddess Kali. The sastras enjoin that one can sacrifice a small goat before the goddess Kali once a month. Nowhere is it said that one can maintain a slaughterhouse in the name of temple worship and daily kill animals unnecessarily. Those who do so receive the punishments described herein.
