If the heart is now dependent on a task, it is like a stream that has no effect.

This profound couplet speaks to the fragility of emotions and the dependency of the heart. Mir Taqi Mir suggests that if the state of the heart (or its emotional fulfillment) relies upon a source—be it a lover, a memory, or an external force—that source must be potent. If that source loses its impact, the entire emotional structure collapses. It's a powerful reminder that true stability must come from within, not from external dependencies.
