Lately in my meditation something very weird has happened, at one point I can't tell if my eyes are open or closed all I see is a lot of light, seemed to start just days after adding the 5 tibetan rites exercises (once again) to my cluttered and numerous middle pillar, psi ball, meditation, and mantra routine. Anyone else had this problem? If it helps I'm on 10 repetitions of each exercise at the moment.
