well said brother.
Especially true for Damo and Nathan, they teach neidan while they have not reach dixian or anything close to that.
They will never even reach renxian by doing those post natal work. what a fraud !
I feel sorry for some folks that can fall for their marketing gimmicks and yet still thinking they are learning Neidan.
Yes, you can learn some meditations etc but it's definitely not Neidan course or perhaps should never called it Neidan in the first place.
However, for JAJ - He used to teach Daoist Mysticism and now been passed down to some of his senior students and the class is to becoming daoist priest in their lineage.
and This is not a Neidan class and mostly the method only post natal work.
