Baal HaSulam, “The Essence of the Wisdom of Kabbalah”: “This wisdom is no more and no less than a sequence of roots, which hang down by way of cause and consequence, by fixed, determined rules, interweaving to a single, exalted goal described as ‘the revelation of His Godliness to His creatures in this world.’”
The wisdom of Kabbalah says that being in our world we can, with the help of consistent study and discovery of the laws of nature, come to the attainment of the upper world, the upper force, the Creator. Moreover, we will reveal Him as an absolute, clear, upper law that connects together all parts of creation. By revealing the Creator, we will fully attain the entire creation because He includes everything.
Everything is inside of Him including us. It is just that on the way to attaining this oneness, this common force, the common system, we get confused in various small, private forces and connections. Yet, in general, we reveal only the Creator because there is none else besides Him.
This is also written, “There is none else besides Him.” This is the first condition of determining what the basis of the wisdom of Kabbalah is. That is, the wisdom of Kabbalah deals with the revelation of the Creator by a person in our world, who in one’s research goes through the entire chain of forces from oneself to the Creator and thus, gradually reveals Him.
