To the seekers of Truth, the Buddha says:
" Do not accept anything on (mere) hearsay- (i.e. thinking that thus
have we heard it for a long time).
Do not accept anything by mere tradition- (i.e. thinking that it has
been handed down through generations).
Do not accept anything on account of mere rumours- (i.e. by believing
what others say without any investigations).
Do not accept anything just because it accords with your scriptures.
Do not accept anything by mere supposition.
Do not accept anything by mere inference.
Do not accept anything by merely considering the reasons.
Do not accept anything merely because it agrees with your pre-
conceived notions.
Do not accept anything merely because it seems acceptable- (i.e.
thinking that as the speaker seems to be a good person his words
should be accepted).
Do not accept anything thinking that the ascetic is respected by us
therefore, it is right to accept his words).
" But when you know for yourselves- these things are immoral, these
things are blameworthy, these things are censured by the wise,  these
things, when performed and undertaken conduce to ruin and sorrow- then
indeed do you reject them."
" 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."
