Believe nothing just because a so-called wise person said it. Believe nothing just because a belief is generally held. Believe nothing just because it is said in ancient books. Believe nothing just because it is said to be of divine origin. Believe nothing just because someone else believes it. Believe only what you yourself test and judge to be true.

Be lamps unto yourselves. Be refuges unto yourselves. Take yourself no external refuge. Hold fast to the truth as a lamp. Hold fast to the truth as a refuge. Look not for a refuge in anyone besides yourselves. And those, Ananda, who either now or after I am dead, Shall be a lamp unto themselves, Shall betake themselves as no external refuge, But holding fast to the truth as their lamp, Holding fast to the truth as their refuge, Shall not look for refuge to anyone else besides themselves, It is they who shall reach to the very topmost height; But they must be anxious to learn.

Whoever has done harmful actions but later covers them up with good is like the moon which, freed from clouds, lights up the world.
