The box and the Sun

The box does not know
of it's permanent lands of shadow
caught deep inside, where light cannot go
yet, the box is simply content though
while the Sun dies daily
giving off light and shadows so gayly
chasing it's own death every single day
just to search for the lost glory stolen away.
The box does not know of glory or shine
but it seems to live just fine
while the sun rises again and again
to falter under it's own hubris not at all thin
yet when the box is opened at last
it accepts the warmth the sun does cast
however the Sun refuses to be caged
so it would seem the shadows remain staged
as the sun dies after such a short span
while the box remains, shadows still in hand
