Kabbalah is the science of how to reach the revelation of the Creator in our world, to feel and grasp Him to such an extent that you can pass it on to other people and to the next generations. Kabbalah teaches how to perceive reality that we cannot feel with the five ordinary senses.
But if it cannot be sensed by our organs of perception, then how can it be perceived by our mind? It cannot! After all, our mind is the result of impressions from our world. As we develop in this world, we build different forms, discernments, and images, all kinds of connections and synapses in our brain.
This is why we are not able to perceive the spiritual world. To do this, we need to develop new organs of perception: to open up new connections between us in our mind and in our heart, which are not present in an ordinary person. But we can do it.
If we gradually build such connections, then they work like synapses in the brain and connect all kinds of concepts and opposites for us. In essence, these are formulas for connecting everything that exists in matter and space.
In this way, we build vessels for perceiving reality within ourselves that is above the corporeal senses and mind, and we begin to feel the spiritual world.
