The exodus to the spiritual world is a slow process. At first, a man is captive of the desires of this world. Gradually, man realizes the aimlessness of his physical existence, that if there isn’t that spark, man is just one of the mill.. Man is confused, hungered (both physically and spiritually), material goals take precedence, so that one may realize how superior spirit is to matter. When one progresses in one’s studies, one sees oneself as more and more corrupt. Ever worse desires are awakened in him. Precisely that is the exile to Egypt, when one who aspires to climb up the ladder to the spirit falls under the rule of the will to receive.
