Question: In what way is the wisdom of Kabbalah different from the rest of the sciences?
Answer: The wisdom of Kabbalah is involved with discovery of the Creator, the discovery of the force of bestowal in those Kelim (vessels) that are in equivalence of form with Him, in other words, Kelim of bestowal. This never can happen in other sciences because they are involved with phenomena that are discovered in receptive Kelim.
In Kelim of bestowal, I discover the higher power. These Kelim are detached from me because I must go out of myself and rise above my desire to receive. This makes it possible for me to comprehend this power objectively, investigate and study it.
In the other sciences, we only discover phenomena that happen within us. This is even though it seems to us that they are happening outside of us in the surrounding world. However, through the wisdom of Kabbalah, we develop new senses, Kelim, in which we discover the higher power that is outside of us.
So, the wisdom of Kabbalah is an objective wisdom about the Creator, about the higher power, about the only power that manages everything, including us, and this is the difference between the wisdom of Kabbalah and other sciences.
The same scientific approach is practiced in the wisdom of Kabbalah as in all the rest of the sciences. As it is written, “A judge has only what his eyes see” (Talmud, Baba Batra 131a), in other words, a factual basis, but they are received in other Kelim, in Kelim of bestowal.
Like every science, the wisdom of Kabbalah develops and discovers more and more. Only after the completion of correction and the discovery of the Light of the Mashiach (Messiah) will the wisdom of Kabbalah become an absolutely complete science.
