Darkness and Light

"God appears, and God is light
to those poor souls who dwell in night,
but does a human form display
to those who dwell in realms of day."

These lines were penned by William Blake,
but others have a different take:
Stare long into the deepest black;
the human mind is winking back.

Whose perceptions can be trusted?
Those whose eyesight has adjusted.
