Mbh 13.115.1

"'Yudhishthira said, "Thou hast told it many times that abstention from injury is the highest religion. In Sraddhas, however, that are performed in honour of the Pitris, persons for their own good should make offerings of diverse kinds of meat. Thou hast said so while discoursing formerly upon the ordinances in respect of Sraddhas. How can meat, however, be procured without slaying a living creature? Thy declarations, therefore, seem to me to be contradictory. A doubt has, therefore, arisen in our mind respecting the duty of abstaining from meat. What are the faults that one incurs by eating meat, and what are the merits that one wins? What are the demerits of him who eats meat by himself killing a living creature? What are the merits of him who eats the meat of animals killed by others? What the merits and demerits of him who kills a living creature for another? Or of him who eats meat buying it of others? I desire, O sinless one, that thou shouldst discourse to me on this topic in detail. I desire to ascertain this eternal religion with certainty. How does one attain to longevity? How does one acquire strength? How does one attain to faultlessness of limbs? Indeed, how does one become endued with excellent indications?"
