I have found the Release Technique to be very helpful. It has the same origin as the Sedona Method, Lester Levenson (the founder of the Sedona Method) left it to two different people who each have their own version of his teachings. I'm sure either one is great but the version in ES is very light so you won't get the full value of it. I realize you've just purchased two courses so perhaps go through those and then see if you want to give the Release Technique or Sedona Method a shot.
Good luck!
