I can't quite place where I have read this, but I'm pretty sure that this is an old old old technique. Maybe in Toltec philosophy. I think they do something a bit different, but I'm pretty sure this is a close to one of their techniques. It's not their recapitulation, but is kind of close, as you are re-writing the memory into a more aware one. In any case, I hope this helps people. With all techniques, it should be done for two weeks daily for a good test. Im doing my own thing for a month or so, every day( consistency).
