The Living Force
Wow, fascinating excerpts! , will be getting this book too! , i also really like his writing style, it's easy for me to follow and he gives good examples..I don't know how we missed it so long!
I think ya'll will be highly gratified to find the scientific backing for much of what Gurdjieff said, as well as what we do here on this forum. You could say that our approach is even better than Gurdjieff's and backed by science.
He also encourages (as we do) gaining knowledge of your psychology/machine as one of the only ways to be able to master any part of it. There are details and studies to fascinate and delight everyone!
