The Zohar tells us about the “next world” and “this world,” but do not think that it is talking about our material world. The Zohar does not say even one word about the physical bodies and what we feel in this world. Everything that happens to us is not taken into account at all in the spiritual.
Everything that happens in the desire to receive for one’s own sake on the still, vegetative, and animate levels of nature is not described in Kabbalah because it is not subject to correction. Only the relationships between people need to be corrected to unification with each other and with the Creator. When The Zohar refers to “this world” or seemingly physical actions and people, it is referring to different types of desires in a person.
Kabbalah engages only in correction of desires. The Creator created a desire, and He wishes to bring it into equivalence with Him. Meanwhile, our physical body is merely our perception of this desire’s existence.
The whole still, vegetative, and animate nature of this world is the most external form of the same desire, which is not subject to correction. In our world there is nothing to correct! The greatest Kabbalist and the most common citizen are made of the same flesh. We can perform organ transplants from one to the other. There is nothing sacred or faulty in these bodies; both of them will die.
Everything starts from the spiritual desire where there is impurity, an intention for one’s own sake against the Creator, and sanctity, a desire for bestowal for the Creator’s sake. However, we are only talking about the desire, not the material body.
It is like placing a special filter in front of me, which holds back the matter of this world and leaves only spiritual matter, the desire for bestowal, in the open. We study the science of Kabbalah, meaning study about those desires that must be brought to equivalence with the Creator, and the other desires will vanish.
