Question: Is the wisdom of Kabbalah a science or not?
Answer: The wisdom of Kabbalah is a divine science, a science of the upper world, and not a regular science. It works with other tools, not like biology, physics, or anatomy. This is a science that is different from all the sciences of this world for it uses different tools and methods.
Although essentially, its goal is not that different. This is because in regular science the person is also subconsciously looking for the Creator, the origin of life. From this yearning he gets a drive for scientific investigation. He feels fulfillment from reaching some kind of truth.
Perhaps this truth is the opposite of the truth, but this is not important. Science has some divine spark in it, and this is what attracts the scientist. The problem is that this spark captivates the person and clothes into his ego so much that it is difficult to extract it.
Nevertheless, by virtue of this spark the scientists are great fanatics of their science. They are ready to sacrifice themselves for its sake, to conduct clinical trials on themselves, and to engage in it day and night. Basically, they are running after the spark that is submerged in the ego, in “Klipa.”
