You can find all of this out with a basic web search.
I did a search just to see what I could find, and after reading for about 2 minutes my brain was about to fall asleep.
I’ve never seen the words “enlightenment” “attainment” “realization” so many times in my life. It was page after page after page of basically NOTHING…no specifics, no examples, no solid directives. Omgosh it was just inane babbling.
No wonder people turn to this stuff out of desperation.
