Hi and thanks Jim. Your post is interesting, too. I distinguish between circumstances and situations (altho the dictionary refers to them as synonyms). The Matrix refers to and captures situations, into which all manner of people can find themselves, bringing along myriad circumstantial details (rich/poor, this or that affliction, family cohesion or dissolution, etc).
Matrix Landings are boundaries but some are interesting. If one lands in Failed dying one automatically gets bounced, likely to other Endstage landings. Some boundaries are fluid in that different folks with different tolerances will define the borders accordingly. In my experiences much of our failures is about not discerning far enough ahead of time to recognize what's happening (or not happening) at some given moment, always in an end of life crucible. The Matix helps us discern things in time to say "you know, I think I'd rather go here, or there..."
