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 speaks about all of reality, and it is revealed to individuals throughout history and in general at the end of our history.
The abundance comes from above and below, there is the desire, a burning need. They cannot touch each other because there is an insulating obstacle between them, an essential precondition of adaptability. This is the main thing that we should know. This is the subject of the wisdom of Kabbalah.
There are many details, but this is what we need first and foremost: knowing how to adapt and make ourselves suitable for the perception of the Creator, for the perception of the abundance.
Accordingly, the Creator is revealed to the full depth of the desire in all its five levels.
As for the roots, we discover them according to Tzimtzum Aleph (the first restriction) and the Masach (screen), and creating the necessary adaptability.
