Mbh 12.15.2b

The Brahmacharin and the house-holder, the recluse in the forest and the religious mendicant, all these walk in their respective ways through fear of chastisement alone. He that is without any fear, O king, never performs a sacrifice. He that is without fear never giveth away. The man that is without any fear never desires to adhere to any engagement or compact. Without piercing the vitals of others, without achieving the most difficult feats and without staying creatures like a fisherman (slaying fish), no person can obtain great prosperity.[35] Without slaughter, no man has been able to achieve fame in this world or acquire wealth or subjects. Indra himself, by the slaughter of Vritra, became the great Indra. Those amongst the gods that are given to slaughtering others are adored much more by men. Rudra, Skanda, Sakra, Agni, Varuna, are all slaughterers. Kala and Mrityu and Vayu and Kuvera and Surya, the Vasus, the Maruts, the Sadhyas, and the Viswadevas, O Bharata, are all slaughterers. Humbled by their prowess, all people bend to those gods, but not to Brahman or Dhatri or Pushan at any time. Only a few men that are noble of disposition adore in all their acts those among the gods that are equally disposed towards all creatures and that are self-restrained and peaceful. I do not behold the creature in this world that supports life without doing any act of injury to others. Animals live upon animals, the stronger upon the weaker. The mongoose devours mice; the cat devours the mongoose; the dog devours the cat; the dog again is devoured by the spotted leopard. Behold all things again are devoured by the Destroyer when he comes! This mobile and immobile universe is food for living creatures. This has been ordained by the gods. The man of knowledge, therefore, is never stupefied at it. It behoveth thee, O great king, to become that which thou art by birth. Foolish (Kshatriyas) alone, restraining wrath and joy take refuge in the woods.
