The Shayar says that he compared the rose to his beloved, and found a great difference in the proximity.

This profound couplet speaks to the bitter reality of disillusionment in love. The poet describes a situation where the beloved initially compliments him, comparing him to a beautiful flower (Gul). He feels validated and close to the love. However, when the beloved actually draws near, the poet realizes there is a vast, unbridgeable gap—a difference between the superficial praise and the cold reality. It is the pain of emotional distance despite physical proximity.
