AHIMSA

Ahimsa is the principle of non-injury.  “All things breathing, all things existing, all things living, all beings whatsoever should not be slain or treated with violence, or insulted or tortured or driven away,” states the Acaranga Sutra of Jainism, the view of Buddhism and Vedanta as well. 

While walking in the forest, for instance, Jain monks carry long staffs which they tap on the ground in front of them to drive off small animals and insects so they do not accidentally get trampled. 

Ahimsa, in addition to physical non-injury, includes mental non-injury, as in the case of what Buddhism calls the destructive emotions, the mental afflictions.  Anger, ill will, hatred, jealousy, resentment are among these.
