Regarding the thought of a breatharian community. I remember Dan Brulé saying there is a sun-eating (not gazing) community in India. When he visits them, no matter if 10 or 2 days, he feels no hunger at all. So I guess a community can definitely help with the „initiation“.

It also reminds me of the 4 Minute mile. For a while it was impossible to run a mile under 4 minutes and once it was done many other people could suddenly do it - nowadays even youth athletes can do it.

PS:
Dan Brulé is probably the best breath teacher in the world. He incorporates Wim Hof, Pranayama, Sufi breathing etc. and looks into the many many many applications of breath in our lives. He’s a Philosopher of the Breath.
