He did come, perhaps for a fleeting whim, but when the breath of my lips was present.

This powerful couplet speaks of complex, bittersweet encounters. The poet acknowledges the beloved's presence, admitting that the visit might have been for a fleeting reason. However, the true turmoil isn't the visit itself, but the moment when the speaker's own lips were radiating a seductive 'breath' (nafas-e-baaz-pusīn). It suggests a vulnerability or a deep emotional entanglement that the speaker himself initiated, making the separation even more painful.
