Baal HaSulam, “Introduction to the Book, Panim Meirot uMasbirot,” p.5: Now you will understand what is written in 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 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, lies the cure that reforms a person.
This power exists nowhere else. No other book, no other means in the world will help us correct ourselves, to come to the general correction and achieve the goal of creation. The only way is to disseminate the wisdom of Kabbalah so that it becomes revealed everywhere, so that everyone will know: There is a means for correction of the world.
Even if everyone is able to realize it only to the extent of his power, there must be awareness that the science of Kabbalah brings us correction. This knowledge is a prerequisite. Even Pharaoh learned what correction is and thus agreed to release the children of Israel. In other words, our egoism will not let us rise above it if we do not receive a clear and accurate idea of the method of correction.
Baal HaSulam writes about this in the article “Messiah’s Shofar:” “We have accepted that there is a precondition for the redemption—that all the nations of the world will acknowledge Israel’s law, as it is written, “and the land shall be full of the knowledge,” as in the example of the exodus from Egypt where there was a precondition that Pharaoh, too, would acknowledge the true God and His laws, and would allow them to leave.”
This applies to our personal Pharaoh, egoism, and to the whole world to which we must convey this knowledge. The world already feels that it needs a certain technique, but how quickly they learn about it depends on us.
