Practical Work on Self.
You used to have to seek, seek, seek, to find any concrete answers about work on self or practical aspects of the Fourth Way. You'd have to make an impossibly huge donation, or climb an unclimbable mountain, or join an organization with rigorously stringent membership qualifications -- just in order to get into a position to maybe possibly ask someone -- if they even knew -- for an exercise to "work on self." Or, if you were able to find a book, then you'd probably have to pass a qualifying test to be allowed to read it.
Now, with no questions asked, with no prerequisite donation or mountain-climbing experience, you can order -- and even get FedEx delivery on -- from amazon.com -- your own private, paperback technical manual of what insiders know to be "The Big 24" exercises, E.J. Gold's Practical Work on Self. (A very fine tool, IMHO :-). )
Before the publication of this book, "the Big 24" exercises were only available in restricted publications and in workshops.
E.J. Gold is bold. In Practical Work on Self, he radically lays out real-life exercises to leverage your attention to be able to observe that elusive human biological machine -- the one, Gold says, that is responsible for keeping us from the waking state of consciousness -- and, if all goes well, also the one that eventually becomes our partner in transformation.
