Dam!
A dam in a river blocks (the natural flow of water) Creates a reservoir To produce hydraulic power A river dammed: A claustrophobic sight Walled up (and waiting) To breathe its suspended sigh Every heart is a river Yet some have been dammed No passage: blockage. Hoarded emotions repressed Those obstructed hearts hoard Their frugal, stingy 'heart-draulic' energy What will happen to that artery? (Will love ever stretch out of such misery?) The dam in the river. The dam in the heart. Consider the river... Consider your heart.
