The Reconnection (training/seminar)
Eric Pearl’s book (by the same name, see above) was one of the first I ran across in my spiritual development journey, and when I found out that a class would be held in Montreal (I was posted to the U.S. Embassy in Ottawa at the time) I signed up. So there I was – an American diplomat sitting in a hall surrounded by dozens of reiki practitioners, chiropractors, integrative nutrition specialists, and yoga instructors – and I loved it. While I didn’t continue down the path to become a healer, this course opened my eyes to what was possible.
Reconnective Healing is all about getting your ego out of the way and letting yourself become a conduit for healing energy. The courses are short (generally just two days) and students can become practitioners after taking the Level 1 and Level 2 courses. Oftentimes the Level 1 and 2 courses (taught at various locations around the country and overseas) are scheduled back-to-back – that’s just four days to change your career and your life. I could recommend reading the first, before taking the course.
