Just raise two issues :
1) WuLiu says that an abrupt , strong erection (of course here referring to male practitioners' ) in our meditation, is a symtom of the birth of Yang (' 陽生' ) ; and , even though we are told that it happens in a mindless status , such a claim is still doubtful , and already criticized by many Taoist masters .
Hi Exorcist... Can you please explain to us in more detail what these criticisms entail? Do they mean that the abrupt appearance of an erection during a mindless state is unlikely to occur, or that such an occurrence does not indicate the birth of yang? Which, if any, texts contain these criticisms?
