What do u think of this quote?

"Kabbalah, in its entirety, is a collection of pagan superstitions which have d into the world of Jewish faith, and which cannot be reconciled with '…the Lord our God, the Lord is One.' The Zohar (the most fundamental Kabbalistic work) was fabricated and written by a certain Moshe DeLeon in Spain in the late thirteenth century… hence, the idea that the Zohar is a 'holy' Tannaic work is nothing but foolishness. The Tannaic Sage, Rabbi Shimon bar Yohai (who lived about nineteen hundred years ago) had no connection with the Zohar whatsoever!" Yeshayahu Leibowitz
