An Opportunity for Redemption
Now you will understand what is written: The Zohar, “With this composition, the Children of Israel will be redeemed from exile.” Also, in many other places, only through the expansion of the wisdom of Kabbalah in the masses will we obtain complete redemption.
They also said, “The Light in it [The Zohar] reforms him.” They were intentionally meticulous about it, to show us that only the Light enclosed within it, “like apples of gold in settings of silver,” in it lies the cure that reforms a person. Both the individual and the nation will not complete the aim for which they were created, except by attaining the internality of the Torah and its secrets.
