In essence, we represent souls rather than physical bodies even now. The Creator created the desire to enjoy, and there is nothing else besides this desire. If we sense certain corporeal matter, it is not because another separate reality exists. There is only desire which feels itself in a physical body. It is the same soul which feels only itself and only within itself. It does not perceive anything outside.
For this reason the soul feels itself as existing in its corporeal body, seemingly surrounded by other, similar bodies. This is how I perceive myself and the surrounding reality since I am enclosed inside myself with my ego. As soon as I begin to acquire new desires and perceive properties outside of myself, I begin to see reality in a different way.
The reality which I see outside of myself is called the “Upper World.” How do I exit out of myself (from my ego) and see the existence outside of myself? I have to connect with other souls, with my friends. Within this connection between us, in greater unity, we reveal common sensations and manifestations called “the spiritual world.”
Therefore, when we read The Zohar, we have to remember that we all desire to reveal the Upper Light, to reveal everything described in The Zohar. It conveys to us the states and pictures which talk only about the connection between us and its various forms. That is the entire reality.
