Question: Is it possible to say that as long as The Book of Zohar was hidden, it was gathering power and energy? Or has humanity developed and reached a height from which it can perceive and understand it?
Answer: There is nothing sacred in a book. We need to understand that the concept of Kedusha (Holiness) means the characteristic of bestowal and love; it is not found in The Book itself and not among its pages. The Book of Zohar serves as a transmitter, a channel through which the higher force passes and influences us.
If the person who reads the text is interested in associating with it, then the text becomes a channel that leads to the upper Light and may not yet be felt by the person himself, but it is already influencing him. The person begins to feel inner changes and even gets used to such an influence from The Book of Zohar.
He later discovers further and further new characteristics, new feelings. And that is how he advances.
