Rebirthing breathwork - seriously, just what is this? Positive/negative experiences, anyone?
I've had experience with this, but first want to share some general info. There are trends, philosophies, belief systems that may not have a direct source that equal say the Vatican for Roman Catholics. We might be able to sort out the origins of some beliefs, even who the main proponents are, but all this New Age stuff keeps moving through cultures (not just California), people combine and morph things how they want to. I think often times the beliefs aren't necessarily the problem, the problem is what folks do with it, how they behave.
So for me personally I tend to watch for cultural rip offs, fraud, and abuse when I look over beliefs, leaders, and groups.
There are many types of "breath work". Many people rip off other cultural practices, package it their own way, and come up with claims of inventing yet another breathing something or other. Rebirthing is one of the types, there are others with other names.
My experience is with Rebirthing and specifically with Leonard Orr. I lived at his community in California for several months, quite awhile ago. He considers himself a guru, he believes he is immortal, he travels the world conning people into giving him their money. He's a jerk. One of many examples: we on staff were told to meet outside at a fire pit and wait for him to show, he'd called a meeting. He was an hour late and he told us that he was late because our energy wasn't right. He then told us that if he hadn't invented fire meditation he would have killed someone by now, because he found humanity so annoying.
Of course, he didn't invent fire meditation. Nor is he immortal.
I've had experience with large group awareness trainings, destructive groups, charismatic leaders, and con artists. They can come in all shapes and forms, some are overtly New Age, some can appear conservative and "normal". I think the trick is to learn the red flags of destructive groups, manipulators, con artists, and ceremony sellers / cultural appropriators.
