I am in the process of reading "The Disappearance of the Universe" by Gary R. Renard and it has me reeling--even though I have studied "Course in Miracles" for over 10 years. It is all about "undoing" everything that we've clutched on to all our lives and sends "religions" spinning down the drain (but not in a judgemental way, of course

It reminds me a little of Neale Donald Walsh's book "Tomorrow's God" because they both turn current belief totally upside down.
Has anyone read read either of these books or studied (read would not be appropriate here) "The Course In Miracles?"
