There's an important piece of history about Rolfing also. When it started, it was more painful than what it is now. The Rolfers decided to cool it a bit with the pain.
The deep and painful nature of it sometimes can cause emotional reactions. Rolfing affects the aura. Unlike the regular body which has a brain, the auric body's memory is not only in the brain, it is in all places of the body. So, you can be getting one of the 10 sessions and when a certain part of your body is massaged deeply, it could bring forth psychological blockages.
Yes, you may cry in front of another man who is giving you the Rolfing session, but it is therapeutic.
(I like the Therapeutae, a mystical community during the time of Jesus. They definitely had a presence in Alexandria. Philo of Alexandria and Eusebius have written about them. They were healers of the soul. Rolfing, again, is beneficial to one's aura. The book, Infinite Mind, has more information.)
The only two books I know that mention it was a book probably written by the person for whom the technique is named. The second book I've mentioned above.
