Regarding the importance of "Ra'aya Meheimna", Rabbi Moshe Cordovero said, "Know that this book, which is called "Ra'aya Meheimna", which Rashbi made with the tzadikim who are in Gan Eden, was a repair of the Shekhinah, and an aid and support for it in the exile, for there is no aid or support for the Shekhinah besides the secrets of the Torah... And everything that he says here of the secrets and the concepts—it is all with the intention of unifying the Shekhinah and aiding it during the exile.
