There is a Sun Somewhere

Block the object of Light,
Yes, You can!
Let the dark clouds hover above the face of the Sun
And seal it's eyes;
What happens then,
Lo, the dark clouds have changed colour
And become white!
Why?
Is it because you can not stop light…
Yes, it's an eternal truth that goes many creations past…
Even the dark most corner of the earth
Knows there is a Sun somewhere…...
