"That wretched man who kills living creatures for the sake of those who would eat them commits great sin. The eater's sin is not as great. That wretched man who, following the path of religious rites and sacrifices as laid down in the Vedas, would kill a living creature from a desire to eats its flesh, will certainly go to hell. That man who having eaten flesh abstains from it afterwards acquires great merit on account of such abstention from sin. He who arranges for obtaining flesh, he who approves of those arrangements, he who kills, he who buys or sells, he who cooks, and he who eats it, [acquire the sin of those who] are all considered as eaters of flesh. [Therefore] that man who wishes to avoid disaster should abstain from the meat of every living creature."
Mahabharata, Anushasana Parva 115.44-48
