What Buddha Said...,

Don't hold on to a belief because of the tradition,
Don't hold on to a belief because it is mentioned in great books,
Don't hold on to a belief because it is suit to our present belief,
Don't hold on to a belief because it is said by a great person,
Don't hold on to a belief because it is said by your teacher,
Suspect it,
Question it,
Investigate it,
Think logically yourself,
When you understand yourself it is true, correct and good - Accept it
When you understand yourself it is false, incorrect and not good - Leave it !

"Kalama Suthra"

Nobody can show such a thinking freedom given in other religions. Not only regarding his teachings, asked his followers to investigate on Load Buddha's life too. He said, that kind of searching gives the perfect opinion whether Load Buddha is enlightened or not. Load Buddha had powers to perform great miracles. But he always said miracles have lower values. Because those powers doesn't mean he is enlightened. He said, people should look at Load Buddha's wisdom, teachings, behavior and his perfection to use as measures of his enlightenment.

According to Buddhism misgiving is not a failing. But need to search and get rid of the suspicion rather than standing on it. Therefore Buddhism is not based on faith. It allows its followers to question. It accepts the devotion comes through the understanding. But it is not like the blind faith.
