The heart, restless and grieving, was like a bloody tear at night, 'Mir'. But when I saw you, the door of the beloved was alight.

This couplet is a profound expression of deep emotional turmoil. Mir Taqi Mir describes his restless heart weeping blood at night. The second line reveals the source of this anguish: seeing the bloody threshold (bismil). It suggests that the mere sight of a painful reality, a threshold marked by sorrow, is enough to break the spirit and cause unimaginable grief.
