Mbh 13.115.2c

That man who abstains from meat, is never put in fear, O king, by any creature, wherever he may be, viz., in terrible wildernesses or inaccessible fastnesses, by day or by night, or at the two twilights, in the open squares of towns or in assemblies of men, from upraised weapons or in places where there is great fright from wild animals or snakes. All creatures seek his protection. He is an object of confidence with all creatures. He never causes any anxiety in others, and himself has never to become anxious. If there were nobody who ate flesh there would then be nobody to kill living creatures. The man who kills living creatures kills them for the sake of the person who eats flesh. If flesh were regarded as inedible, there would then be no slaughter of living creatures. It is for the sake of the eater that the slaughter of living creatures goes on in the world. Since, O thou of great splendour, the period of life is shortened of persons who slaughter living creatures or cause them to be slaughtered, it is clear that the person who wishes his own good should give up meat entirely. Those fierce persons who are engaged in slaughter of living creatures, never find protectors when they are in need. Such persons should always be molested and persecuted even as beasts of prey. Through cupidity or stupefaction of the understanding, for the sake of strength and energy, or through association with the sinful, the disposition manifests itself in men for sinning. That man who seeks to increase his own flesh by (eating) the flesh of others, has to live in this world in great anxiety and after death has to take birth in indifferent races and families. High Rishis devoted to the observance of vows and self-restraint have said that abstention from meat is worthy of every praise, productive of fame and Heaven, and a great propitiation by itself. This I heard in days of old, O son of Kunti, from Markandeya when that Rishi discoursed on the demerits of eating flesh.
