I find it useful to have a simple overview of the whole system (that's not a system). I'm attaching a schematic representation of The Fourth Way that I've pieced together over the years. I find that it helps me keep on track. I wonder if it might be helpful to others!
Mr G always warned against a mechanical representation of the teachings. I hope that this escapes being mechanical through being deliberately vague as to details.
