I suspect that's because these topics aren't discussed nearly as frequently as others here.

My input as a non-religious, non-psychedelic user who has done some breathwork: it is simply changing something about the normal functioning of the body (such as oxygen levels) and does induce a mildy altered (but pleasant) state of consciousness for me.

Can you explain how exactly that process happens? The article is still really vague about it, as are most people here. Is it about forcing yourself to hyperventilate? Or forcing your breathing to be at a certain rhythm, regardless of what the rest of your body demands naturally? And how does the music come into play here?

Also, is it dangerous? I know the human body is very sensitive to abnormal blood saturation, so I'm curious what it can do to you.
