Altered states of consciousness induced by breathwork accompanied by music

The last time this topic was on HN, some mentioned that many indigenous people had similar techniques with drum beats, e.g. https://www.youtube.com/watch?v=bIfLC5iudQ0 (this is a modern rendition though).

See also: sweat baths. Surprisingly wide spread in practice. Not only is it practiced throughout most of North America (Turtle Island) but is also a feature of Kabbalistic (Jewish mysiticist) practices. Mandingo practices might be an African analogue.

(yes, they can lead to psychedelic experiences)

EDIT: here's a paper on Kabbalah and sweat lodges https://www.academia.edu/37069129/The_Kabbalah_of_the_Sweatl...
