if the injured man returneth his injuries: if the chastised person chastiseth in return; if fathers slay sons, and sons fathers and if husbands slay wives, and wives husbands; then, O Krishna, how can birth take place in a world where anger prevaileth so! For, O thou of handsome face, know that the birth of creatures is due to peace! If the kings also, O Draupadi, giveth way to wrath, his subjects soon meet with destruction. Wrath, therefore, hath for its consequence the destruction and the distress of the people. And because it is seen that there are in the world men who are forgiving like the Earth, it is therefore that creatures derive their life and prosperity. O beautiful one, one should forgive under every injury. It hath been said that the continuation of species is due to man being forgiving. He, indeed, is a wise and excellent person who hath conquered his wrath and who showeth forgiveness even when insulted, oppressed, and angered by a strong person. The man of power who controleth his wrath, hath (for his enjoyment) numerous everlasting regions; while he that is angry, is called foolish, and meeteth with destruction both in this and the other world. O Krishna, the illustrious and forgiving Kashyapa hath, in this respect, sung the following verses in honour of men that are ever forgiving, 'Forgiveness is virtue; forgiveness is sacrifice, forgiveness is the Vedas, forgiveness is the Shruti. He that knoweth this is capable of forgiving everything.
