This Wall that Surrounds Your Heart

This wall that surrounds your heart,
What is required to break it down?
The heat of a flame to melt through the steel,
or a steady hand, to dismantle each brick.
Maybe this wall is not that strong,
and takes just a gentle breath to blow it free.
When your heart is discovered, what will it be?
A wasted muscle that has never loved,
or a cavity full of pain and sorrow.
