As we rise above egoism, besides everything else, we make a wonderful discovery: We begin to discern that essentially, the entire world exists within us, and not outside of us. And this is logical because I really don’t know what exists on the outside.
A person only perceives what enters his senses and through the nervous system reaches his brain, which processes the final “image.” This is the way we perceive the world. It is enough to sever a nerve to make a part of our reality disappear from our senses.
Thus, as a person rises above himself, he sees that his perception is not at all on the outside, but fully depends on his senses, desire, thought, sensations, and mind. And when we know how to change these parameters, we can expand our perception and rise above the limits of the five senses.
This is where the name “the wisdom of Kabbalah” comes from, which literally means the wisdom of “reception.” A person uses it to gradually come out from the physical senses of his animalistic body and expand the sensations to the point of infinity. While living in our world, he advances to the level where he no longer associates himself with a corporeal body since he sees a much greater reality above it.
Now he no longer conditions his life to perception in the five senses. And even after the body dies, the person remains in the reality he has acquired above it. He does not feel death since a new dimension has entered his perception before the death of the body.
This way a person lives on two levels: the corporeal degree, like all of us, and the “incorporeal” degree that rises above egoism.
