When I asked for the trace of the song of love, the morning breeze scattered it with a handful of dust.

Mir Taqi Mir captures the ephemeral nature of love here. The poet asks the breeze about the traces (nishan) of his journey through love. But the breeze, carrying a cloud of dust, simply blows those signs away. It suggests that the memories and signs of deep love are so fragile and transient that they cannot be held onto, vanishing as easily as dust in the morning air.
