My Answer: The Zohar says that when the students of Rabbi Shimon were getting ready to study, they would conceal their hatred for each other and would look for ways to feel love above the hatred. This love is the result they demanded from the study (see The Zohar, Chapters “Ki Tissa (When You Take),” Item 54 and “Aharei Mot (After the Death),” Item 65). And indeed, the miraculous force contained inside the Kabbalistic texts brought them that love and they rose above their initial, natural hatred. Moreover, the hatred was not revealed to them accidentally, but as a result of their study and great efforts.
When a Kabbalah Convention takes place, it is a very significant event that causes a person to go through many states. One cannot always be in a state of ascent where he deems bestowal and spiritual ascent above all the earthly things.
A large assembly of people attracts a powerful Light by virtue of their common desire, and this Light begins to “shake them up.” This is why the people there go through many contradictory states: love and hate, understanding and confusion, joy about how fortunate you are to be there, and the next moment, you find yourself wondering what you are doing there at all. This is the manner in which spiritual states are quickly processed within us. You go through more states in one day of the Convention than in half a year of study during regular life!
Nevertheless, in order to use the time of the Convention most effectively, one must go through these states consciously and be ready for them. Thus, everything depends on one’s preparation to the Convention.
