Each thing that G‑d created has its own realm. There is a world in which it exists, and a world in which it does not.

Ideas exist in a world of intellect. In the world of a creature who knows nothing but emotion, ideas do not exist.

Emotions exist in a world of sentience. In the world of the physical elements—the world of the rock and the water, of wind and of fire, the world of Newtonian mechanics—emotions do not exist.

Words exist in the world of language. In the world of a horse, words and sentences are no more than the neighing of human beings. In the world of the horse, words do not exist.

G‑d is not a word, not a feeling, not an idea, not a symbol of anything else. G‑d is the essential reality of all things and of each thing.

G‑d is everywhere.
