Regular science is already coming closer to a worldview akin to spirituality. Everything in science is unifying and erasing all boundaries, generating such phenomena as chemical physics and physical chemistry. Scientists continue to discover new forces, as though delving deeper into the picture of the world with a microscope and revealing new elements in it. However, all of these elements belong to one common source.
In essence, each and every form of matter – positive, negative, and neutral elementary particles – expresses different forms of the same idea or force. However, for the time being we are unable to see nature "in the middle line," and we constantly perceive it "from the right" or "from the left." It seems to us that nothing exists in the middle, as if zero, while in truth there cannot be zero. Consequently, science will come to the eventual conclusion that matter should be examined from above down, rather than from below upward, that is, from matter itself.
This is what happens with Kabbalah studies. A person works hard on examining his or her material, which is the desire to receive pleasure. He tries to fill it somehow, but as a result, comes to a complete breaking and reveals that it is impossible to do anything with oneself. Then a person turns to the Upper degree and asks it to be revealed, wishing to receive the same form as the Upper in order to reveal one’s lower degree.
Modern science is coming closer to revealing the fact that unless we, the observers, raise ourselves to a higher degree, there will be no understanding of our present degree. The science of Kabbalah addresses this problem at the outset. Kabbalah explains that if a person remains on the same degree, one will be unable to reveal a thing. It teaches: "Rise higher, and there you will attain the force that controls you; it is the same force that built and now leads you through all the states you are experiencing.”
Hence, although science has not yet reached its final stage of development (it is only coming closer to this), it will eventually reveal that we have to rise to a higher degree in order to understand something in ourselves. All of reality is contained within our desire, so will we really benefit by revealing thousands of additional phenomena in it or discovering more elementary particles in quantum physics? It is impossible to unite all of the parts together without understanding the Force that controls everything. This constitutes the entire problem in attaining the higher degree, which moves our whole reality.
Kabbalah, on the other hand, places the goal of attaining the Creator, the Upper degree, before a person immediately. Moreover, it is a completely scientific approach since while remaining submerged in our material we cannot attain this material; we need to rise to the level of forces.
