Mahavira

All breathing, existing, living, sentient creatures should not be slain, nor treated with violence, nor abused, nor tormented, nor driven away.

Do not injure, abuse, oppress, enslave, insult, torment, torture, or kill any creature or living being.

Can you hold a red-hot iron rod in your hand merely because some one wants you to do so? Then, will it be right on your part to ask others to do the same thing just to satisfy your desires? If you cannot tolerate infliction of pain on your body or mind by others' words and actions, what right have you to do the same to others through your words and deeds?

Do unto others as you would like to be done by. Injury or violence done by you to any life in any form, animal or human, is as harmful as it would e if caused to your own self.

Desistance from sin makes one entirely happy.

Anger begets more anger.

Non-violence and kindness to living beings is kindness to oneself. For thereby one's own self is saved from various kinds of sins and resultant sufferings and is able to secure his own welfare.

A living body is not merely an integration of limbs and flesh but it is the abode of the soul which potentially has perfect perception (Anant-darshana), perfect knowledge (Anant-jnana), perfect power (Anant-virya), and perfect bliss (Anant-sukha).

In happiness and suffering, in joy and grief, we should regard all creatures as we regard our own self.

Kill not, cause no pain. Nonviolence is the greatest religion.

A man is seated on top of a tree in the midst of a burning forest. He sees all living beings perish. But he doesn’t realize that the same fate is soon to overtake him also. That man is fool.
