If that radiant face comes beneath those twisted and winding locks of hair, it will be as though the sun has returned once again into the zodiac sign of Virgo.

In this couplet, the poet crafts a delightful astronomical metaphor around the beloved's beauty. In classical poetry, 'sunbul' (hyacinth) symbolizes dark, curling tresses, while 'burj-e-sunbula' refers to the zodiac sign Virgo. The poet imagines that if the beloved's radiant, sun-like face is veiled beneath those winding curls, it would be as if the sun itself has journeyed back into the constellation of Virgo.
