"Anybody who gives you a belief system is your enemy, because the belief system becomes the barrier for your eyes, you cannot see the truth. The very desire to find the truth disappears. But in the beginning it is bitter if all your belief systems are taken away from you. The fear and anxiety [...] will surface immediately. [...] only the search for truth and the experience of truth — not a belief — is capable of healing all your wounds, of making you a whole being."

Who said it and in what context it is irrelevant. I only quoted it because I find it the most compact and well put form of the idea.

LE: removed all the preachy stuff as advised by mod. Might have been a little too much anyway.
