How old and how fast can they stay before you go?

Question

the sister of whirlpools,   
that dance together,       
down the river stream
the teeth of a yueh fish,   
poke over the edge      
 putting a stop to the swirls
as the wind begins to face ,  
the ripples of a thousand suns
Born on the tip of a jade leaf
The purple silk flaps along,   
to the bird song
the two legs that carry,   
this mountain melody
The yueh closes its jaw
takes a leap off the creek   
and dives into yesterdays rice fields
All thats left is a few bubbles   
that return to the stream
A riverbank rebirth for   
the forehead that almost       
tastes the sun.
There are words the wind   
doesn’t want written
