The Kalama Sutta is the Buddha's reply.
- Do not believe anything on mere hearsay.
- Do not believe in traditions merely because they are old and have been handed down for many generations and in many places.
- Do not believe anything on account of rumors or because people talk a a great deal about it.
- Do not believe anything because you are shown the written testimony of some ancient sage.
- Do not believe in what you have fancied, thinking that, because it is extraordinary, it must have been inspired by a god or other wonderful being.
- Do not believe anything merely because presumption is in its favor, or because the custom of many years inclines you to take it as true.
- Do not believe anything merely on the authority of your teachers and priests.
- Do not accept any doctrine from reverence, but first try it as gold is tried by fire
The same text, said the Buddha, must be applied to his own teachings.
