However you put it, faith or belief as understood by most religions has little to do with Buddhism.
The question of belief arises when there is no seeing – seeing in every sense of the word. The moment you see, the question of belief disappears. If I tell you that I have a gem hidden in the folded palm of my hand, the qustion of belief rises because you do not see it yourself. But if I unclench my fist and show you the gem, then you see it for yourself, and the question of belief does not arise. So the phrase in ancient Buddhist texts reads: “Realizing, as one sees a gem in the palm.”
A disciple of the Buddha named Musila tells another monk: “Friend Savittha, without devotion, faith or belief, without liking of inclination, without hearsay or tradition, without consideration apparent reasons, without delight in the speculations of opinions, I know and see that the cessation of becoming is Nirvana.
And the Buddha says: “O Bhikkus, I say that the destruction of defilement and impurities is meant for a person who knows and who sees, and not for a person who does not know and does not see.”
It is always a question of knowing and seeing, and not that of believing. The teaching of the Buddha is qualified as ehi-passika, inviting you to ‘come and see’, but not to come and believe.
