Answer: I would not recommend it; this will cause harm. How can there be a critical approach? Someone who doesn’t understand the upper world doesn’t have the tools in his hands for criticizing things.
In the wisdom of Kabbalah there is no concept of a “critical approach” because anyone who attains the upper world understands what it is talking about. And someone who has not attained can criticize as much as he wants, that is his own business, but he is only harming himself.
I am amazed at your words! How can you evaluate a book that speaks about things you do not understand at all? In doing so, you bring it down to the level of ordinary philosophy or mysticism.
