I originally ran across the Law of One reference in the book, "Edgar Cayce on Atlantis" back when I was in 8th grade (1971), ten years PRIOR to the Ra contacts, and well before the Internet and home computers. So I do not tend to attach "Ra" as the author of the concept, as most people do these days, equating the "Ra Material" with the "Law of One". (And no, I don't believe Wilcock is the reincarnation of Cayce, either.)
The original definition from Cayce is:
A good summary of Cayce's reference can be found in Geoffrey Keyte's "Edgar Cayce'sEdgar Cayce wrote:The WHOLE law is to love the Lord thy God with all thy heart, thy mind, thy body; thy neighbor as thyself. This is the whole law, this is the whole purpose for an experience, an activity of an entity in any given or individual experience or appearance even throughout the sojourns in a material plane.
Cayce 1464-2
Vision of Atlantis".
I didn't even discover the Ra material until my association with ISUS led to our having a membership meeting at L/L Research in 1997. I wasn't really in to "channeled" stuff back then, as there was just too much channeled "trash", where you could obviously see the bias of the instrument, trying to promote their own ideas as some superior, extraterrestrial knowledge... but Ra stood out in one, important concept... he was NOT "politically correct" with scientific references. He made statements that contradicted modern, scientific knowledge (like hot, blue stars being OLD, instead of young...) that caught my attention, because Larson made the same claims... and Ra was supporting those statements.
How did you come to discover the Law of One?
