It is an illusion that I am in my own attire; look closely and see if there is anything in me.

This profound couplet speaks of self-perception versus external gaze. The speaker suggests that the beloved's belief—that he is merely in his own clothes—is an illusion. He challenges the beloved to look deeply into his being, asking if they can find any truth or remnant of the person they once knew. It’s a poignant moment of emotional withdrawal, forcing the beloved to confront the possibility that their memory of him is flawed.
