A person having his being under the influence of evil Karma, must always consider how he can atone for his Karma, and extricate himself from an evil doom, and the evil Karma may be expiated in various ways. Accordingly, O good Brahmana, I am charitable, truthful, assiduous in attending on my superior, full of respect towards regenerate Brahmanas, devoted to and free from pride and (idle) excessive talk. Agriculture is considered to be a praiseworthy occupation, but it is well-known that even there, great harm is done to animal life; and in the operation of digging the earth with the plough, numberless creatures lurking in the ground as also various other forms of animal life are destroyed. Dost thou not think so? O good Brahmana, Vrihi and other seeds of rice are all living organisms. What is thy opinion on this matter? Men, O Brahmana, hunt wild animals and kill them and partake of their meat; they also cut up trees and herbs; but, O Brahmana, there are numberless living organisms in trees, in fruits, as also in water; dost thou not think so? This whole creation, O Brahmana, is full of animal life, sustaining itself with food derived from living organisms. Dost thou not mark that fish preys upon fish, and that various species of animals prey upon other species, and there are species the members of which prey upon each other?
