" . . . The wind changes round, and I stir
Within another's life. Whose life?
Who is dead? Whose presence is living?
When may I fall strangely to earth,
Who am nailed to this branch by a spirit?
Can two bodies make up a third?
To sing, must I feel the world's light?
My green, graceful bones fill the air
With sleeping birds. Alone, alone
And with them I move gently.
I move at the heart of the world.
