In the rime of the ancient mariner how does the mariner describe his current life?

Since this incident, the Mariner at uncertain hours is terrorized by this memory.
"Since then, at uncertain hour,

That agony returns:

And till my ghastly tale is told,

This heart within me burns. "

So now he must tell this story to others to relieve the pain of his memory.

"I know the man that must hear me:

To him my tale I teach. "
