"Close your eyes for about a minute and simply notice what your mind does. Stay on the lookout for any thoughts or images, as if you were a wildlife photographer waiting for an exotic animal to emerge from the undergrowth. If no thoughts or images appear, keep watching; sooner or later they will show themselves — I guarantee it. Notice where those thoughts or images seem to be located: in front of you, above you, behind you, to one side of you, or within you. Once you’ve done this for a minute, open your eyes again. That’s all there is to it. So read through these instructions once again; then .... give it a try.
