Baal HaSulam, “Preface to the Wisdom of Kabbalah,” Item 11: Now you can understand the real difference between spirituality and corporeality: Anything that contains a complete desire to receive, in all its aspects, which is Behina Dalet, is considered “corporeal.” This is what exists in all the elements of reality before us in this world. Conversely, anything above this great measure of desire to receive is considered “spirituality.” These are the worlds ABYA—Above this world—and the whole reality within them.
There, where the desire to enjoy, the intention to receive for oneself, reigns, where personal gain exists, where I look at reality, myself, the world, and the others through the egoistic paradigm, through the intention of “what can I get from this?” that is inherent in me, there, I see the corporeal world. I was born and grew up like this, and I cannot look at anything differently.
I recognize only what appears good to me and useful or dangerous and harmful. In short, I see only what my desire to enjoy can get pleasure from or what it should move away from to avoid suffering. I do not notice to whom I can give, and I see only from whom I can receive. This picture presented before me is called “this world.”
If I change my paradigm, my perception of reality, and wish to look from the point of view of to whom and how much I can give, then I already see the future world, above our world. Then, of course, I see other forms, different relationships, which I imagine in spirituality. This is called the spiritual world.
