When my sorrow pulls the stream, a noise arises from the sky.

This profound couplet speaks to the sheer magnitude of emotional expression. When the inner turmoil or joy (the 'noise') of the heart rises up, it is so immense that even the mundane elements—the drains and gutters—react to it. It suggests that the emotional reality of the lover is powerful enough to disturb the very fabric of the environment. A beautiful depiction of overwhelming feeling.
