Rabash, Shlavey HaSulam (Steps of the Ladder), Article "Above Reason in Divine Service": I will only put my faith in the sages, who have told us that the Creator indeed hears our prayers. This is called faith above reason.
A person has to try to clearly reveal for himself that the Creator hears one’s prayers. Until it happens, he advances as though he has already revealed it.
Here, everything depends on the correction of one’s Kelim (vessels). If a person does not yet see something, it doesn’t mean that it doesn’t exist in reality. The broken glasses are not an indication that the world has become depleted. I imagine to myself that the things I saw before still exist.
But what should I do if I’ve never seen them before and still don’t have the glasses? Then I have to follow the advice of the sages. Otherwise, how will I be able to discover anything?
I recall that when I was 11, all of a sudden they told me: "You need glasses." At first, I didn’t realize why and what for, especially because back then children wearing glasses wasn’t very common. With difficulty, my parents found a suitable pair for me; when I finally put them on, I was surprised to see things that escaped my sight before.
The same happens in spirituality: I have to trust the experts who tell me that I have to acquire a new instrument of perception, a spiritual Kli (vessel), and then I will recover my sight. This instrument is not obtained instantly, but by way of multiple actions. I perform them in order to see a new world; I act by using the force called "faith in the sages."
They said: "It’s worthwhile for you to get new glasses; you need them." I don’t feel it; I have never experienced the spiritual world to lack it now. Yet, I still follow their advice.
