Indeed, the book is so deep and wise that evidence that it was written by one of the forty-eight prophets would make more sense than attributing it to one of the Tanna’im. Moreover, if I became convinced that Moses himself received [the Zohar] on Mount Sinai from God Himself, I would be satisfied. This book is worthy of that. Once I was able to prepare this accessible commentary, enabling people to understand what the Zohar says, I no longer feel any obligation to investigate the [identify of the] author. No one who understands the Zohar could doubt that its author is anyone less than the great Tanna, the holy Rabbi Shimon bar Yoḥai.
