Quick info on the M-set: Wikipedia

Traditional representations of meditating practitioners of Taoist "internal alchemy" (nei-tan) bear a striking resemblance to the representation of the M-set.

It is possible that the representation of the M-set is to be usefully related to the traditional concept of an alchemical "vessel" in which all "base matter" can be dissolved... - source
Ever since I used ayahuasca the M-set has struck a chord with me. It is a deeply alchemical journey to partake of that drink, as is studying the M-set... I have no doubt about that. Not sure how to apply it yet... too close at the moment to see the big picture so I am just posting this to see what comes back.
