I love this poem and I think its beautifully written, but I'm having a hard time understanding it.

IN PRAISE OF PAIN

A brilliance takes up residence in flaws—
a brilliance all the unchipped faces of design
refuse. The wine collects its starlets
at a lip's fault, sunlight where the nicked
glass angles, and affection where the eye
is least correctable, where arrows of
unquivered light are lodged, where someone
else's eyes have come to be concerned.

For beauty's sake, assault and drive and burn
the devil from the simply perfect sun.
Demand a birthmark on the skin of love,
a tremble in the touch, in come a cry,
and let the silverware of nights be flecked,
the moon pocked to distribute more or less
indwelling alloys of its dim and shine
by nip and tuck, by chance's dance of laws.

The brightness drawn and quartered on a sheet,
the moment cracked upon a bed, will last
as if you soldered them with moon and flux.
And break the bottle of the eye to see
what lights are spun of accident and glass.

I perceived it as saying that there is beauty in pain and in flaws. Pain makes a person vulnerable and thus human. It makes us stronger and helps us grow as a person. Without it we cannot heal and learn.

Please help, and tell me your understanding from the poem. What did you get from it? What do you think it means?

THANKS!
