Mbh 13.116.2c

While dwelling in the uterus, all creatures are cooked in the fluid juices, that are alkaline and sour and bitter, of urine and phlegm and faeces,--juices that produce painful sensations and are difficult to bear. There in the uterus, they have to dwell in a state of helplessness and are even repeatedly torn and pierced. They that are covetous of meat are seen to be repeatedly cooked in the uterus in such a state of helplessness. Attaining to diverse kinds of birth, they are cooked in the hell called Kumbhipaka. They are assailed and slain, and in this way have to travel repeatedly. There is nothing so dear to one as one's life when one comes to this world. Hence, a person of cleansed soul should be compassionate to all living creatures. That man, O king, who abstains from every kind of meat from his birth, without doubt, acquires a large space in Heaven. They who eat the flesh of animals who are desirous of life, are themselves eaten by the animals they eat, without doubt. Even this is my opinion. 'Since he hath eaten me, I shall eat him in return,'--even this, O Bharata, constitutes the character as Mansa of Mansa.[525] The slayer is always slain. After him the eater meets with the same fate. He who acts with hostility towards another (in this life) becomes the victim of similar acts done by that other. Whatever acts one does in whatever bodies, one has to suffer the consequences thereof in those bodies.[526] Abstention from cruelty is the highest Religion. Abstention from cruelty is the highest self-control. Abstention from cruelty is the highest gift. Abstention from cruelty is the highest penance. Abstention from cruelty is the highest sacrifice. Abstention from cruelty is the highest puissance. Abstention from cruelty is the highest friend. Abstention from cruelty is the highest happiness. Abstention from cruelty is the highest truth. Abstention from cruelty is the highest Sruti.
