The Light acts on our will that is similar to Him. This measure of congruence of the will to the Light is called faith. If I read Kabbalistic sources with a purely egoistical desire and purpose, they will not affect me.
The point in the heart is a broken point; it draws a person to spirituality but only because he feels bad. He isn’t yearning, yet, for the “Good that does Good,” for bestowal and love. So far, he merely isn’t satisfied with earthly life: The future is dark and life has no purpose. These simply provide an egoistic motivation for seeking spirituality. But the Light cannot affect such desire even from afar. It acts on the will according to the measure of faith in it, that is, it acts only on one’s yearning for bestowal.
Faith is tested by a person’s devotion to the path and purpose. One must check the purity of his intention to attain the quality of bestowal. Faith itself, the attribute of bestowal, is received from Above as a reward for efforts made. When one is deserving, then the “night” will end and he will see “the light of day.”
If a person uses Torah for his own egoistical fulfillment, it becomes the potion of death for him. This means he is not only “spiritually dead,” but also he is “drugged” by death because he thinks that it is spiritual life! He raises his egoism even higher and cannot believe that he is living in deception.
Exit into the truth: If we do everything together, if everyone receives from all others such forces that one can easily demand the Surrounding Light (Ohr Makif) to act on him, then the path becomes a wonderful adventure. Just cling on to each other!
If you stay alone, there immediately grows a wall before you. If you unite with the others in order to walk together, the wall immediately falls and spreads itself into a wide highway. There is either a wall or the highway. The choice is to be among friends each moment or not. Everything is done by the Upper Light; we must obey only this one condition.
