What is Attention?

What is attention?
At this moment, dear reader, place your attention on the sounds in the space where you are sitting as you read these words…
Now place your attention on the overall posture and position of your body, the muscular tensions produced by the posture…
Now place your attention on your hands…
Now place your attention on your breathing…
Now on your heartbeat…
And now back to the sounds in the environment.
What is happening? What is it that moves? What is it that does the moving? What is the nature of this phenomenon?
What is attention?
