In the abstract world of emotions, ideas, and the soul, many things can overlap in time and space.
But the physical world is a place where everything says, "In my place, nothing else can exist.".
When a human being does not allow the spiritual light of their soul to shine, they are transforming into a physical object. Then they say, "You are taking up my space.".
How vast is the space a human being occupies? As much as they can take in, and more. We are all descendants of Adam, and he occupied the entire world.
But when human beings rise a little higher, become a little more spiritual and a little more sensitive to the world around them, then they say, "Let's share this space. There's room for all of us.".
