Giving up killing, you give freedom from fear to all the beings in cyclic existence. You will be praised in the present life, have a beautiful countenance, enjoy bright faculties, and carry out acts that engender longevity.
If day and night you protect even harmful creatures of different kinds, you will thereafter be protected, and when you separate from your body, you will be born in the joyful realms.
If you want to experience such ripening, then know that these fruits are proportionate to your diligence.
—Buddha Shakyamuni, Āryasaddharmasmṛtyupasthāna
