Outside paths (Taoism) [Middle]

There are over 300 fallacious techniques in the 84 schools of sexual intercourse, with 36 methods of culling the female principle. As in the previous grade, technical terms are given biological associations and practices include ingesting sexual material such as placenta and one's own seminal fluid. The outside paths are deviations from the way.

In the nine grades of practices which are side tracks and auxiliary methods in Taoism, this is the middle of the three lower grades.
