I've had this poem in the works for almost a year. I kept adding bits of description, clarifying metaphors and analogies, fussing with parallels... I couldn't make up my mind whether it was about the church, or politics, or science. I dug it out last week, and started cutting all the preachy stuff. It's up to you, the reader, to decide what it's about. 

 A rock, rough and rugged.

crashed into a rushing river.

The river pulled back,

waves roiling away from the intruder.

But the river forgave the rock,

wrapped its long blue arms around the newcomer,

hugged it, caressed it, invited it to travel

down to the sea....
