This man is maybe one of the best and most experienced breathworker on the planet.
He met so many people like Leonard Orr, the founder of rebirthing, he met the phenomenal yogi Babaji from haidaikhan.
In this video he talks, teach how to do vivation, a breathing technique derived from rebirthing.
This rebirthing technique (holotropic breath, transformational breath, vivation...) use circular breathing (connected breath) to heal emotionally and bring many physical, emotional, spiritual or personal development benefits.
Rebirthing is often used to remember your birth and heal from trauma.
In general it's done with a qualified breathworker for the most fast and impressive result but here Dan teaches how you can try by yourself.
