Your belief or your disbelief is not going to make any difference to the truth. Truth is truth, whether you believe or you disbelieve.
But if you believe in something it starts appearing as true to you at least. That's what the meaning of belief is: belief means to believe in something as true -- you know that you don't know, you know that the truth is unknown to you, but in your ignorance you start believing, because belief is cheap.
To discover truth is arduous, it needs a long pilgrimage. It needs a great emptying of the mind, it needs a great cleansing of the heart. It needs a certain innocence, a rebirth: you have to become a child again.
Only very few people have ever dared to discover truth. And it is risky, because it may not console you; it has no obligation to console you. It is risky: it may shatter all that you have known before, and you will have to rearrange your whole life. It is dangerous: it may destroy all your illusions, it may shatter all your dreams. It is really going through fire; it is going to burn you as you are, it is going to kill you as you are.
