Energized Hypnosis is a collaboration between Christopher Hyatt and Calvin Iwema. Very fun to read as the text is very highlighted and uses NLP language patterns. I thought since I didn't get much out of the Undoing exercises I still might give this a try and didn't regret it. The book is quite short and you go through it in a breeze.
I also really enjoyed the audio hypnosis change session by Calvin Iwema which brought me quite deep (though I was already quite high from other meditations before so will see how another session goes tomorrow and let you know.) It also features a HILARIOUS mp3 of Israel Regardie's Guru Hymn to the Grinning Giggling Monkey-Faced Guru!
