I have said what needed to be said; nothing more can be spoken. One remains, the other has gone; the river's waves adjust themselves.

This passage suggests that the core truth has been revealed by the Shayar. Kabir feels that the essential message has been delivered, and no further words can change the natural course of things. The metaphor of the river's waves adjusting beautifully captures the idea that life, once a truth is established, simply flows and adapts, accepting what has happened.
