Really nice essay, Bruce.  I think you're right to suggest TSK future-infinitive time and triple-loop awareness are very similar.  And I think both go beyond Tolle.  TSK nicely loops both past and future into the present as One Thing, the future being that sense of indeterminacy and unfinishedness, if you will, and “aliveness” (as you well put it) that turns what once were perceived as solid lines into permeable dashed lines.

I'll come back with more observations, and some connections I can draw with Bohm's understanding of time.  Nicely done, Bruce!
