Enter Mo Pai: The Ancient Training of the Immortals
Why it is on this list
The fullest book-length treatment of the training after Danaos, by an author whose background is in Western hermetics, Taoist nei gong, Tibetan alchemy and kundalini yoga rather than in the Mo Pai lineage. It covers the first four levels in depth and sketches the remaining sixty-eight, and its analysis of how yin and yang qi are gathered and combined is the reason it is cited so often in the online discussion.
