You asked the river

"Who are you?"

The river answered:

What a human question
Am I the water flowing beneath your feet?
Am I the mouth that gives birth to me?
Am I the branches that reach into the sea, becoming something new?
Am I the droplets that shape me, an ever-moving snake from the bird's eye?
Am I the earth and the rocks under the water, the bed that gives me space to move?
Am I the picture in your mind of a place that never changes, still in its meaningless movement?

Am I not all these things at once?
Am I not the same as you, ever-changing and infinite?

Let me ask you a question, then.

The river says,

Who are you?
