I checked a book out from the library called Body Types, by Joel Friedlander. It was published in 1986, is based on Gurdjieff's Fourth Way, and covers body types such as Lunar, Venusian, etc. If I study this book, will it send me in the wrong direction when it comes to Michael Teachings, as in, did MT break away somewhat from these ideas or change or expand on them? The only thing I know at this point is that the names of the body types are the same in the book and MT.
