I’m an atheist and therefore not Buddhist, but the quote below by Buddha is amazing:
“It is proper for you, Kalamas [the people of the village of Kesaputta], to doubt, to be uncertain; uncertainty has arisen in you about what is doubtful. Come, Kalamas. Do not go upon what has been acquired by repeated hearing; nor upon tradition; nor upon rumor; nor upon what is in a scripture; nor upon surmise; nor upon an axiom; nor upon specious reasoning; nor upon a bias towards a notion that has been pondered over; nor upon another’s seeming ability; nor upon the consideration, ‘The monk is our teacher.’ Kalamas, when you yourselves know: ‘These things are bad; these things are blameable; these things are censured by the wise; undertaken and observed, these things lead to harm and ill, abandon them.
“…Do not accept anything by mere tradition… Do not accept anything just because it accords with your scriptures… Do not accept anything merely because it agrees with your pre-conceived notions… But when you know for yourselves?these things are moral, these things are blameless, these things are praised by the wise, these things, when performed and undertaken, conduce to well-being and happiness?then do you live acting accordingly.”
I think everyone should follow this advice. And if after questioning everything you end up believing in a certain religion or god, then I’ll respect your beliefs even if I don’t agree with them.
