Baal HaSulam, “Introduction to The Book of Zohar” section 71: The reason for their words is, as we have explained, that when all those who engage in the Torah degrade their own internality and the internality of the Torah, leaving it as though it were redundant in the world… by that, they intensify their own externality.
Also, the externality in the nations of the world—the destructors among them—intensify and revoke the internality among them, which are the righteous of the nations of the world.
Additionally, the externality of the entire world, being the nations of the world, intensify and revoke the children of Israel—the internality of the world.
In such a generation, all the destructors among the nations of the world raise their heads and wish primarily to destroy and to kill the children of Israel.
Each of us remainders should take upon himself, heart and soul, to henceforth intensify the internality of the Torah, and give it its rightful place, according to its merit over the externality of the Torah. And then, each and every one of us will be rewarded with intensifying his own internality, meaning the Israel within us, which is the needs of the soul over our own externality, which is the nations of the world within us, that is, the needs of the body.
Also, the internality of the nations of the world, the righteous of the nations of the world, will overpower and submit their externality, which are the destructors. And the internality of the world, too, which are Israel, shall rise in all their merit and virtue over the externality of the world, which are the nations.
At the end of the “Introduction to The Book of Zohar,” Baal HaSulam emphasizes only one thing, what do we learn: internality or externality?
Together with this, our study is connected directly to realization. If we learn externality, then we realize externality, and if we learn internality, then we realize internality. And in this way, we really transform the world from its feet to its head or from its head to its feet.
Everything depends only on this. Learning correctly makes it possible for us to attract the Light that Reforms, and so we begin to understand more and to organize ourselves and the whole world according to the higher power.
Here the explanations of Baal HaSulam leave us no possibility of evading the answer. He puts things very clearly. So each and every one, as much as he is prepared, must be involved with the internality of the Torah, its inner message and realization by using The Book of Zohar and all the books of Kabbalah that Baal HaSulam and Rabash wrote so that we will influence ourselves, the whole world, and all of us together found in a single system.
