It has been over 12 years since I've read the Bob Monroe books, and now they have a new home with a friend in Florida.
Didn't Bob predict the passing of the rogue "star" Nibiru in one of his books??? It only occurs once every 3,000 years and the Higher Intelligent Beings said that they were gathering to view it???? :o

  Doesn't ring a bell whatsoever.  The Gathering, as Bob seem to have described it, was a period of great change and potential, the degree of which hasn't been seen for a very long time--i remember something about some "millions" of years. 

But it wasn't attributed to anything "physical".  Just a sort of great cycle with many alignment points so to speak.

  And yes, many other Consciousnesses from many other systems were said to be interested in observing this period or cycle, presumably to see how humans will handle it.  I believe Bob or his guidance specifically said something about great crisis or potential.
