Question: If today Kabbalah is open for everyone, then what is its secret?
Answer: There are no secrets in Kabbalah and never have been. The entire problem is only in society’s possibility of correctly accepting it, adapting to it, tasting it, and using it correctly for its development. There is nothing else.
For example, it is written in The Book of Zohar that of the great Kabbalist Rabbi Shimon’s ten disciples, only Rabbi Aba could correctly expound upon it so that it would be accessible, smooth, correct, and at the same time hidden.
And the measure of concealment must be so special that when you read the Kabbalistic text, it reveals itself to you, and maybe not to your neighbor.
