Shadows

Shadows exist because there is an opaque object and there is a directional light source.

There is nothing good or bad about shadows.

It is just inherent in the nature of things and in their interactions.

If the object is transparent or if the light is omnipresent or omnidirectional, then there are no shadows.

In the beginning God created the heaven and the earth.
And the earth was without form and void,
and darkness was upon the face of the deep.

[Gen 1:1-2]
