Sorry for my laziness, but there is a painting of Seth that looks exactly like Robert A Monroe somewhere out here. I'm just saying. :)
this is what comes up if you google image "seth speaks"
on the assumption that reality is true (focussing on the underlying reality, rather than teachers), each teacher brings a different perspective on the same reality (PMR + NPMR and beyond)
Tom's uniqueness appears to me to be 2-fold vs the various 20th century mystics
#1 - he is an active secular OBE'er rather than a channeller or medium (though this ground is already well covered by Monroe and other TMI writers)
#2 - he is a physicist with the tools to map NPMR and integrate this exploration with the secular religion of science, unifying the right and left hemispheric approaches, eliminating a huge source of entropy in individuals and in the overall system.
This is more than an incremental step in efficiency, but is rather an exponential paradigm shift...like the invention of the transistor.
what was previously intuited or accepted on faith, can now be experienced directly and proven, with a model that explains the empirical evidence to tie it all together.
what does this mean for us personally?...it may all boil down to paying increasing attention to that higher (HS) voice that whispers in our ear at each point in our day's decision tree, and increasingly giving the finger to the other voice(s), the impulse of ego (and the R-complex).
the irony is that all the things the grasping ego wants, may appear without effort once we get with the program, which is an observation the Nazarene made.
like the monkey trap, grasping the nut prevents us from eating it.
