Question: If Kabbalah is the method to discover the Creator, why was it concealed for two thousand years, preventing people from using it?
Answer: It was a latent period in the history of Kabbalah, like the Middle Ages.
To us, it seems like nothing happened during the Middle Ages. Development in Europe appeared to freeze, but this was not so. Experts will tell you it was a period of rapid development, but it was internal, hidden. It prepared Europe for all the subsequent progress. Without this preparation, there would have been no cultural or industrial revolution. no Renaissance, nothing.
Question: If our development were not technological, what would it be?
Answer: Our development had to be technological because it was the result of our egoistic development.
Today, this period is coming to an end. The next stage will be spiritual development. We are gradually entering it now. Our recognition of the evil of our current development will lead us to it.
