This technique is based on the Lifeline program at The Monroe Institute.
He has written several books about this subject and leads 10 to 15 workshops annually, teaching participants how to perform those retrievals.
Moen has also stated that he is working on an "Afterlife Communication Device," like a "telephone" which will enable direct communication with the deceased without the need for special esoteric knowledge or techniques.
