Destiny

"Vyasa said,

'It behoveth thee not, O monarch, to indulge in such poignant grief. I shall repeat what I have once said. All this is Destiny, O puissant one! Without doubt, all creatures that are born display at first a union (of diverse materials and forces). Dissolution. however, overtakes them at the end. Like bubbles in the water they rise and disappear. All things massed together are sure to crumble away and all things that rise must fall down. Union ends in dissolution and life ends in death.

I had heard that my father had been devoured by a Rākṣasa employed by Vishwamitra: violent anger seized me and I commenced a sacrifice for the destruction of the Rākṣasas: hundreds of them were reduced to ashes by the rite, when, as they were about to be entirely exterminated, my grandfather Vasishtha said to me: Enough, my child; let thy wrath be appeased: the Rākṣasas are not culpable: thy father's death was the work of destiny. Anger is the passion of fools; it becometh not a wise man. By whom, it may be asked, is anyone killed? Every man reaps the consequences of his own acts. Anger, my son, is the destruction of all that man obtains by arduous exertions, of fame, and of devout austerities; and prevents the attainment of heaven or of emancipation. The chief sages always shun wrath: be not subject to its influence, my child. Let no more of these unoffending spirits of darkness be consumed. Mercy is the might of the righteous
