Hi everyone. When you press your eyes with the fingres you observe a curious tapestry of colors like the mandalas with rectangles colored and coloured lines.Then the whole thing is transformed to a sun wich is divides to four or eight with a very bright center. The same phenomenon appears behind my closed eyelids during the time of exit or during meditation. Its maybe a stimulation of the optical nerves or any other idea?
