Q: Man is born in our world through the joining of a physical body with its spirit, which may already be at a certain level in the spiritual worlds, meaning, by definition, it can already have a screen. Why, then, is there a need to start from the beginning in the physical world?
A: Every birth in our world signifies a correction of the corporeal level of desires. Even if a person studied Kabbalah in the past and reached a certain level, but not a final one, that person must be born as a baby, suffer, learn, and arrive at Kabbalah from the beginning. But the student will very quickly return to the level of the previous life and continue from there. There is never a repetition, only new corrections and additions to the previous life.
