Question: If Kabbalah, its Light, develops strong egoism within a person and between us, is there a chance that this process might get out of control and destroy the people or the group with a wave of built-up egoism, leaving only hatred, malice, and disappointment behind?
Answer: Naturally, strong hatred, malice, and disappointment will begin to increase. But usually, it is manifested to the degree that we can counter it in order to progress us in the middle line.
Therefore, among students in each group, there will be contradictions, misunderstandings, and hatred, like with the students of Rabbi Shimon who wrote The Book of Zohar. Nonetheless, this process will not get out of control because everything is given in its proper measure. Every situation that arises can be solved or it would not have been given. Everything is done according to the concept: “Do not place obstacles before a blind man.”
