So whenever I do energy work (I'm now on Day 22 of Mastering Astral Projection), I almost always get the camera flash strobe that goes on and off a few times and stops right about the time I stop. I know this camera flash third eye strobe can be developed into a sort of mirror you can see into with your mind's eye, as well as that it is an indication your brow center is higher developed than average, but I don't know how exactly I can turn this flash (which I started to see on Day 21 of MAP) into something more, like the mirror a.k.a. vision screen. So how do I develop the flash into a vision screen?
