I think that Centerpointe is the best method because all you have to do to initiate it is listen to the cds. This circumvents all the built in resistance and denial that we must usually deal with in beginning and maintaining a personal growth system - and which frequently sabotages us just when we finally reach a little paydirt because of the discomfort of our feelings. As this is usually subconscious and supported by rational excuses we have concocted, we are usually helpless to fight the urge to quit. With Centerpointe, the relative ease of use is its greatest asset.
I find Sedona to have great value as an adjunct, but as mentioned earlier there is another similar method called Focusing based on the book by Eugene Gendling. I find Focusing to be very effective and very cheap as compared to Sedona. Ten or twelve bucks versus hundreds.
My recommendation is Centerpointe, Focusing, and a peppering of paraliminals.
