IF: [ Love is not] Caged

Lubok Omphalos, Q. Cassetti, 2010, pen and inkLove’s a fire that needs renewal    
Of fresh beauty for its fuel:    
Love’s wing moults when caged and captured,    
Only free, he soars enraptured.         
Can you keep the bee from ranging,    
Or the ringdove’s neck from changing?    
No! nor fetter’d Love from dying    
In the knot there’s no untying.
