Blue-Ray souls and seeing Blue.

[Sagittarius]

On seeing auras, "focusing/defocusing" your eyes is more sort of just confusing your system, not really opening you up to energies lol. That being said, retraining the cones and rods of the eye does help, there is a physiological component.
Also, it's probably worth being aware of the phenomenon of phosphenes so it and auras don't get mixed up. http://en.wikipedia.org/wiki/Phosphene

Rie, that's really intersting

My theory so far is the phosphenes create a backdrop or canvas of geometrical mesh which the visual stimuli is translated onto from the mind. The focusing/de-focusing is not just physiological the same thing happens with mind. It's basically meditation, focus to sharply and all you see are phosphenes spinning, unfocus to much and the image is to chaotic and broad, in the middle I get a synthesis of the narrow and broad view which seem to be the perfect perspective for images to form using the phosphene overlay and current input of mind at the time.
