Jainism
Main principles
The principle of ahimsa (non-violence or non-injury) is a fundamental tenet of Jainism. It holds that one must abandon all violent activity and that without such a commitment to non-violence all religious behavior is worthless. In Jain theology, it does not matter how correct or defensible the violence may be, one must not kill or harm any being, and non-violence is the highest religious duty. Jain texts such as Acaranga Sūtra and Tattvarthasūtra state that one must renounce all killing of living beings, whether tiny or large, movable or immovable. Its theology teaches that one must neither kill another living being, nor cause another to kill, nor consent to any killing directly or indirectly. Furthermore, Jainism emphasizes non-violence against all beings not only in action but also in speech and in thought. It states that instead of hate or violence against anyone, "all living creatures must help each other". Jains believe that violence negatively affects and destroys one's soul, particularly when the violence is done with intent, hate or carelessness, or when one indirectly causes or consents to the killing of a human or non-human living being.
