Question: Can you prove the existence of the soul?
Answer: In the wisdom of Kabbalah there are no proofs. Someone who wants to hear will hear. It is impossible to prove anything to a person as long as he doesn’t feel the higher world, and he can feel it only if he opens his senses to absorb the higher state. Here I can help him, but as long as this doesn’t happen, he will not see anything.
Question: Does a person need luck for this to happen?
Answer: He needs luck, happiness, and he needs a special sign from above.
