Hello Sir Edwin, you sound like me!! Dianetics and Scientology, Holosync, Abraham, .... have you listened/applied Eckhart Tolle?
I used Bradley Nelson's Emotional codes (it takes like 2 minutes) and have had such tremendous change! And it's lasting!! I believe the Healing Codes are similar, but I haven't learned the exact process yet. I believe it's like what the Middle East Indians have know for centuries.... everyone has a path, they just aren't all the same path, thus their acceptance of over 400 different religions. I try what indicates to me and it usually works!! Those that don't indicate to me, well, I'm glad they're out there for those they will work with.
