I am not yours, not lost in you,
Not lost, although I long to be
Lost as a candle lit at noon,
Lost as a snowflake in the sea.
You love me, and I find you still
A spirit beautiful and bright,
Yet I am I, who long to be
Lost as a light is lost in light.
Oh plunge me deep in love — put out
My senses, leave me deaf and blind,
Swept by the tempest of your love,
A taper in a rushing wind.

by Sara Teasdale

I do love this poem. Because it does not rhyme, because it will not obey. Because by its very construction it references its own argument.  This is what poetry is meant to do.
