Answer: That is what is said until we attain Gmar Tikkun (the end of correction). It’s said, “Don’t believe in yourself until your dying day.” This means that until all his egoistic desire has finally died, it’s forbidden to believe in yourself.
It’s impossible to know what tomorrow will bring. This is what the entire spiritual process is like. Each time an entirely new world is revealed to you. And everything that you previously saw within your desire to receive, even though it’s partially corrected, can transform the next day into something completely different, and thus we discover new and different connections and horizons.
Therefore, each new level is revealed only in “faith above reason,” in bestowal. A person needs to annul himself and be included into the upper level like an embryo in the mother’s water. It’s only in this way that he is able to discover it. This means to be ready for anything by completely annulling himself.
Thus the Kabbalists write, “As it seems to me,” or “according to my humble opinion.” After all, no created being has attained complete Gmar Tikkun, when for him the whole world needs to be corrected. And even if a person attains his private Gmar Tikkun, it still doesn’t determine the general level and no one knows what can be revealed in it.
