Believe nothing merely because you have been told it. Do not believe what your teacher tells you merely out of respect for the teacher. But whatsoever, after due examination and analysis, you find to be kind, conducive to the good, the benefit, the welfare of all beings — that doctrine believe and cling to, and take it as your guide.
Tenzin Gyatso, His Holiness the 14th Dalai Lama:
We must conduct research and then accept the results. If they don’t stand up to experimentation, Buddha’s own words must be rejected.
