Mbh 3.207.1b

And such a man is not at all considered to have partaken of animal food, even, as a Brahmacharin having intercoursed with his wife during the menstrual period, is nevertheless considered to be a good Brahmana. After consideration of the propriety and impropriety of the matter, this rule has been laid down. King Saudasa, O Brahmana, when under a curse, often used to prey upon men; what is thy opinion of this matter? And, O good Brahmana, knowing this to be the consequence of my own actions, I obtain my livelihood from this profession. The forsaking of one’s own occupation is considered, O Brahmana, to be a sin, and the act of sticking to one’s own profession is without doubt a meritorious act. The Karma of a former existence never forsakes any creature. And in determining the various consequences of one’s Karma, this rule was not lost sight of by the Creator. 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?
