from the teachings of Rebbe Nachman of Breslov translated by Rabbi Aryeh Kaplan
Faith is a very strong thing, and it can greatly fortify your life.
If you have faith, then you have a source of comfort and inspiration even when troubles strike. You realize that all troubles are ultimately for your good and are an atonement for your sins. You know that G-d will be good to you in the end, both in this world and the next.
The faithless skeptic, on the other hand, has nowhere to turn when troubles strike. He is utterly alone, without comfort or inspiration.
It is impossible to put everything into writing, but an intelligent man should be able to build upon this himself.
The main thing is innocent faith. With it, one can have a portion both in this world and the next. Happy is he who has such faith, for he shall never be moved.
There are souls conceived in absolute holiness. When such a holy soul comes down to this world and is not tainted with sin, it results in a person with perfect faith. Such a person never has any doubts.
Others can express their skepticism in such a man's presence, but his faith is no way disturbed. He is totally oblivious to all doubts. His ears are deaf to all their speculation and confusion.
Even one who is not endowed with such an extraordinary soul can realize that the average person's questions are mere foolishness. Upon close examination, their questions turn out not to be questions at all.
Many people are disturbed by questions for years, not realizing that their questions are actually answers. It is only their lack of intelligence that makes them seem like questions in the first place.
They have questions like those one might ask a child: "If we have a broken window, why replace it with a pane from the next window if a bird can then fly through the remaining empty frame?"
Such a question actually includes its own answer. But a child does not realize this and considers it a very difficult question. He will ponder it and not know what to reply.
But the question itself is really very foolish. The question about the bird is really the answer to the first foolish question. The reason why we do not use the adjacent pane is precisely because it leaves a space through which a bird can fly.
A young child does not have enough intelligence to realize that the answer is included in such a question. For this very reason, the question seems very difficult to him.
The same is true of many people. A foolish question enters their mind, and they have no idea that this question actually includes its own answer. It seems like a difficult question, but only because of their lack of intelligence. Understand this well.
Consider all this and be strong in faith. Flee from this foolishness and confusion, and cast all questions and doubts from your mind.
