What has reached my heart, my dear, that it touches the stars, you yourself taught me this art of composing verses and songs.

This couplet beautifully captures the feeling of immense achievement mixed with profound dependence. The speaker marvels at the fact that his art—his song (or ghazal)—has reached the stars. But the wonder quickly turns into a realization: this talent, this entire art form, was taught only by the beloved. It is a humble acknowledgment that even the greatest success is often a gift, a legacy, or a teaching received from another soul.
