Buddha

Don't believe something just because you heard it.
Don't believe something just because everyone talks about it.
Don't believe something just because it's written in your religious books.
Don't believe something just because your teachers and masters say it's true.
Don't believe in traditions just because they've been passed down from generation
to generation. But, after much analysis and observation, if you see that something
agrees with reason and leads to the good and benefit of all, accept it and live it.
And the greatest virtue of the strong is forgiveness.
