What kind of metaphor is "trees in the wind"?
I saw God in the Forest
Teachin' Tai Chi
To the trees in the wind
Bowing to the sea
Excerpt from http://www.bensollee.com/panning-for-gold
What I find odd is that the reference is "trees in the wind" and not just a word and the referee is not obvious, because it doesn't seem to be comparing it to anything and the intended can be just "trees moving with the wind" instead of "tree in the wind" as if the trees are flying in the wind. What's the intended effect and what kind of metaphor is this if it indeed is a metaphor? I am talking about "trees in the wind" specifically and not "teachin' Tai Chi to the trees in the wind".
