A Meditation on Wounds

Some Wounds Heal Best Opened - by Joseph Bishara
--------------------------------------
Some wounds heal best opened
So their poisons melt in the sun
And their deep evils die in the open air
Until the cleaning's all done.

Clean wounds are closed and mended
Never to be opened again
For once the healing is ended
The hole is made whole once again.

I wrote this as I was thinking about bacteria in a puncture wound (e.g. an animal bite). I wonder if, by analogy, this poem holds true for psychological wounds as well.
