Answer: Frankly speaking, I, with my little spiritual attainment, cannot afford to rate Kabbalists. Indeed, despite the fact that I feel, comprehend, attain, and dwell in some spiritual space, I am in it at the level of a fifteen-year-old boy in our world.
What can I say about it? In the spiritual world when you comprehend even at such a level, it gives you the feeling that you are just a young person, you still don’t know much, and therefore, you cannot open your mouth, criticize, or give any assessment.
Can I criticize such great Kabbalists like my teacher Rabash and his father Baal HaSulam or those who preceded them: Baal Shem Tov and the Ari? They are all in absolute attainment of the Creator. Therefore, I have nothing to say in this matter.
I accept their books as absolute knowledge. Those are people who made no mistakes in rising to their level, and their level is practically in the Final Correction (Gmar Tikkun).
The only difference between them is that each attained it from the root of his soul, so there is a difference in the presentation. But for me, it is actually good. I read from one angle about the attainment of the upper world, then from another, from a third, and it develops me.
