The Buddha is the founder of Buddhism. He said:
Do not accept anything on mere hearsay (i.e., thinking that thus have we heard it from a long time). Do not accept by mere tradition (i.e., thinking that it has thus been handed down through many generations). Do not accept anything on account of rumors (i.e., by believing what others say without any investigation). 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 merely considering their appearances. Do not accept anything merely because it agrees to your preconceived notions. Do not accept anything merely because it seems acceptable (i.e., should be accepted). Do not accept anything thinking that the ascetic is respected by us (and therefore it is right to accept his word).
What do you think the Buddha meant by this?
