Khizr, upon that green scroll, is now so keen / The tune of consuming one's own poison, unseen.

This profound couplet speaks of a deeply internal conflict. The speaker acknowledges that even wise figures, like Khizr, are drawn to the seductive 'green path'—a path of temptation or false hope. However, the speaker makes a stark declaration: their current obsession (धुन) is not with external escape, but with the self-inflicted pain of consuming their own poison. It is a moment of ultimate, tragic self-realization.
