The Book of Zohar, “YaYera, Item 114: “When Adam HaRishon sinned, he sinned with the tree of knowledge of good and evil, as it is written, ‘but of the tree of the knowledge.’ And he sinned in it and caused death to the whole world.”
The world is everything I feel. When, on a spiritual level, I started to use my egoism, then immediately my world, all my sensations were reduced from the huge, higher, immense, eternal, perfect state in which I was to a small, flawed, egoistic, dim, temporary world, which quickly ends with my death.
This is exactly what happened in the sensations of people who fell from the spiritual level to the corporeal one.
I feel the whole world inside me. Everything that enters my senses is formed, added up, integrated within me, and is given to me as a picture of my universe, my world, what I absorb into myself.
If however, spiritual sensory organs are formed in me and they are practically immense, then I seem to get out of myself, out of my limitations, and I start to perceive nature in its eternal perfection.
