From Jainism's Holy Akaranga Sutra: Book I – Lecture 3, ”Hot and Cold”, Part 1 of 2

The condition of living beings arises from karma. Examining karma (retribution) and the root of karma, namely killing, examining it and adopting its contrary, he is not seen by both ends. Knowing this, a wise man who knows the world and has cast off the idea of the world, should prudently conquer the obstructions to righteousness. Thus I say. And the hero should conquer wrath and pride. Look at the great hell as the place for greed. Therefore the hero abstaining from killing, Should destroy sorrow, going the road of easiness. Here now the hero, knowing the bondage, knowing sorrow, should restrain himself. Having risen to birth among men, He should not take the life of living beings.
