First dont shoot the messenger.
Dr David Hawkins is I believe a Mystic of our time and claims that there is a method of telling truth from false hood as in his Books "Power versus Force" and "Truth versus Falsehood"

When you go there please also go to the about section.
Dr Hawkins can remember all past lives and is in the state of full Enlightenment, there are levels of enlightenment.
He has developed a map of consciousness and way of calibrating all levels of consiousness.
He claims that the Bible and various other Holy Books calibrate highly but that "Revelations" is of a very low calibration and was actually channeled from the lower astral and is not concordant with the teachings of Christ which are of course valid. The Old Testiment except for Genisis Proverbs and Psalms also calibrates low as it depicts an angry paranoid judgmental god which is far removed from the truth and teachings of Jesus.
I realize these statements are controversial and will not debate them as I personally dont know. I can only point to the life work of Dr Hawkins who is in his 80s now and still dedicated to raising the consciousness of mankind.
