The stain that was on my head, O candle, kept consuming me all the way down to my feet.

This powerful couplet speaks of a consuming passion or flaw. The stain ('daag') that initially appeared on the head—representing the mind or the initial attraction—gradually spread, consuming the poet's entire being until the very feet. It is a profound meditation on self-destruction through love, where the mark of love is inescapable and all-encompassing.
