poem!!!!!!!!!!!!!!!1

請問這首詩,除了字面上的意義之外,還有什麼比較deep的 meaning...
A blade of grass
You ask for a poem. I offer you a blade of grass.
You say it is not good enough. You ask for a poem.

I say this blade of grass will do. It has dressed itself in frost,
It is more immediate Than any image of my making.

You say it is not a poem, It is a blade of grass and grass
Is not quite good enough. I offer you a blade of grass.
