Imagine yourself as a child lying on your back, gazing up
into a cloudless sky, and blowing soap bubbles through a
plastic ring. As a bubble drifts up into the sky, you watch
it rise, and this brings your attention to the sky. While
you are looking at the bubble, it pops, and you keep
your attention right where the bubble had been. Your
awareness now lies in empty space.
