Stand close to a mirror and look yourself in the eye. You're looking out through the pupil of your eye. This is a basic assumption. The eye in the mirror's pupil is a black hole. I suggest staying with this meditation for some time.
The photo above was taken by double exposing an eye (Mary Jane's, a frequent victim of my photos) with the image of rain on a car window. It was done by running a role of Tri-X film through a camera twice. Of the 20 or so exposures, only this one was usable.
