The purple strobing started one afternoon when I was preparing dinner for my family. I screamed in shock, realizing I'd awakened my auric vision, which lasted the entire weekend. It gently faded over time, but I could revive it to full strength by performing your spinal column technique for a few minutes. The auric sight is now permanent and no longer wavers, in fact, doing the Kundalini technique you showed me actually opened my astral vision too, and I can see spirits, which was very alarming at first.
