Literally, the couplet means that the meeting in the eyes was an illusion every moment, and suddenly, that beloved companion was no longer present.

This powerful couplet captures the sudden, brutal realization of betrayal. The poet, Mir Taqi Mir, describes the deceptive nature of the beloved's gaze—it always seemed like a lie. But the pain deepens when, just as suddenly, the familiar, comforting presence vanishes. It's the pain of illusion shattered, the sudden loss of what you thought was real.
