My 2 cents here!
Regarding Damo's method:
-It's not expensive, so paying a year in advance it's not dauting.
-The syllabus is huge, way too much for the average student, if you want foundations, I'd stick to the wuji and dantian gong, with a dash of jibengong, daoyin, and five elements. There are so many exercises and ancillary methods that it would be easy to get lost.
-The weekly leak of content is a bad idea for qigong. Foundations need doing the same thing for a lot of time. Weekly content is always adding fluff to keep you interested, but being easily bored is a bad thing for a cultivator. Half of the lessons arent really needed, they are filling space.
-Damo itself is the reason I decided to put the method aside. I'm not a monk and dont care about his antics with alcohol and cigars, but if you compare stuff from a few years ago, you can see his body deteriorating. He had a worm that made him go through a scrawny phase, but now he is recovered and that cant be an excuse anymore. He has issues with his physical body
Regarding Nathan's
-The method is expensive, each course costs you more than a year with damo.
-The online courses are poor. The books are way better. The courses are basically Nathan's audio files of training sessions. If you are willing to spend a few days, you could do your own files by recording the instructions in the books. The end result would be almost the same at a fraction of the cost. If you want to join his method, I'd do retreats with him, ignoring the online stuff.
-Same as Damo, Nathan is the reason I didnt go further into the method. Nathan looks extremely weak and emaciated. I don't understand how he could develop yin yang fusion and advanced microcosmic orbit and not look healthy at all
