Taken from the Amazon review for The Law of One (the Ra Material):
"I discovered this material in the early '80s about the time it was released. I was blown away then and still am. I'll never forget the feeling - something similar to having uncovered a profound and precious secret. I remain convinced that other than ACIM, this may be the ONLY channeled material out there that is what it purports to be. Much more recently, I've begun kinesiologically calibrating books, people, spiritual teachers, institutions with the method taught by Dr. David Hawkins. The Law of One books collectively calibrate (or they did with my calibration) at over 800, in fact somewhere in the neighborhood of 850 if I remember correctly. Astounding, considering that Hawkins states that less than 5% of channeled material calibrates over 455."

Transcending the Control System: Standards of Channeling
"There exists no perfect channeled material since corruption is inevitable. Ego biases, mistranslations, quantum laws interfering with transmission of quantitative data, hacking by negative entities, programming of the channeler through abductions and implants, etc… can all cause degradation in the conduit over time. And of what material is published, perhaps just a few percent fall within the top three levels of standards. So as much as channeling can be a valuable source of inspiration and insight, I advise extreme discernment and a high set of standards when approaching it."
the rabbit hole just gets deeper and deeper...
