In the non-physical world of emotions, ideas, and the soul, many things can overlap in time and space. But a physical world is a place where each thing says, “In my space, nothing else can be.” When a human being doesn’t allow the spiritual light of his soul to shine, he too becomes a physical object. So he says, “You are taking up my space.” How large is the space of a human being? As much as he can grab and more. We’re all reproductions of Adam, and there was only one of him occupying the entire world. But when a human being rises a little higher, a little more spiritual, a little more sensitive to a world beyond him, then he says, “Let’s share this space. There’s room here for all of us.” Maamar Issa B’Zohar (Hosafot, Kuntres Hechaltzu).
