The heart that was often under the dust, had some temperament that was destined these days.

This couplet speaks of emotional awakening. The poet suggests that the heart, which was previously dormant or neglected ('under dust'), was destined to experience a specific, powerful mood during a certain time. It’s the feeling of rediscovering a profound emotion—a passion or sorrow—that was merely sleeping within you. Mir Taqi Mir beautifully captures this moment of unexpected emotional destiny.
