The dancer performs with such precision that not a single item falls or slips from her body. Even the water in a cup does not spill, nor does a drop fly away, as she dances.

This couplet marvels at the incredible balance and precision of a tightrope walker. It paints a picture of such perfect control that nothing on her body, not even a tiny object, moves or falls as she dances on the rope. The second line further emphasizes this mastery by saying that if a cup of water were placed upon her, not a single drop would spill or splash out, despite her active performance. It's a beautiful metaphor for immense focus, steadiness, and skill, demonstrating how profound concentration can achieve seemingly impossible feats of stability and grace even in the most delicate situations.
