Answer: This always happens. To rise above the next stage, you must destroy the previous stage inside yourself. Therefore, the parents, so to speak, die in a person, and the next degree arises inside him.
Abraham was not supposed to kill his son. He only had to restrict him in his movements. After all, Abraham is the right line, complete bestowal, and it cannot rise and do something if there is no next, left, egoistic force against it.
This is why there must be a restriction, the thing that is imposed on egoism, from the right line to the left one. Thus, the totality of the forces gathering inside him begins to manifest in a person.
