Hi, I just found this site & love it!
Right now I'm reading Transcending The Levels of Consciousness(The Stairway to Enlightenmnet) by David R. Hawkins, M.D.,PhD This is his fifth book - the first was Power vs Force.
He and his research team have calibrated levels of consciousness & throughout his works, he suggests lots of ways to move beyond thoses levels - it's all fascinating to me & so helpful.
