One time, when the Buddha passed through the city of Kalama, people asked him: "So many gurus were here and all of them gave us excellent teachings, but they contradict each other. What should we do?" The Buddha then gave the so-called Kalama Discourse and expounded on ten aspects that one should consider when listening to spiritual teachings.
Summarised, the Buddha said:
"Do not believe a spiritual teaching just because:
1. it is repeatedly recited,
2. it is written in a scripture,
3. it was handed from guru to disciple,
4. everyone around you believes it,
5. it has supernatural qualities,
6. it fits my beliefs anyway,
7. it sounds rational to me,
8. it is taught by a respectable person,
9. it was said to be the truth by the teacher,
10. one must defend it or fight for it.
However, only when it agrees with your experience and reason, and when it is conducive to the good and gain of oneself and all others, then one should accept the teachings, and live up to them."
