From the letter, the strength of your beauty's veil has now lessened, the desire that was like Joseph's has now become the desire for Rustam. This suggests that the initial, soft admiration inspired by beauty has been replaced by a stronger, more passionate, or perhaps challenging desire.

This profound couplet speaks to the changing nature of desire and beauty. Mir Taqi Mir suggests that the subtle, delicate charm ('safa-e-husn') that was once evident through mere letters has now faded. The poet contrasts the gentle, yearning love of Yusuf (Joseph) with the powerful, almost aggressive passion of Rustam. It’s a realization that attraction has evolved from tender longing to a much more forceful, demanding obsession.
