Don't believe a teaching just because you've heard it from a man who's supposed to be holy, or because it's contained in a book supposed to be holy, or because all your friends and neighbors believe it. But whatever you've observed and analyzed for yourself and found to be reasonable and good, then accept that and put it into practice.
Gautama BuddhaIn what is seen, there should be just the seen; In what is heard, there should be just the heard; In what is sensed, there should be just the sensed; In what is thought, there should be just the thought. He should not kill a living being, nor cause it to be killed, nor should he incite another to kill. Do not injure any being, either strong or weak in the world.
Gautama Buddha
