I've read it. BUT... practicing ho'oponopono tends to make my life hang a sharp left into "help, everything sucks!" and I don't seem to be able to help anyone else with it either. I think I must be doing it wrong.
And this "zero state" sounds cool, and Richard Bartlett talks about it too, and I sort of suspect that this is also Abraham's Vortex concept, but I haven't found it yet.
