The Law of One series

The Law of One books were channeled by Carla Rueckert, Don Elkins, and Jim McCarty between 1981 and 1984. If you do not have copies of these books, you can order one or all (there are five) from L/L Research or their online store. They can also be downloaded as pdfs from L/L Research's library.

Because the books are transcripts of tape-recorded exchanges, they tend to jump around from topic to topic. As a result, it can be difficult to find the particular thought you are looking for. To make searches easier, I built a searchable database.

"... Our research group uses what I prefer to call “tuned trance telepathy” to
communicate with an extraterrestrial race called Ra...
Ra landed on Earth about 11,000 years ago as a sort of extraterrestrial
missionary with the objective of helping Earthman with his mental
evolution. Failing in this attempt, Ra retreated from the Earth’s surface but
continued to monitor activities closely on this planet. For this reason Ra is
highly informed about our history, languages, etc.
Probably the most difficult thing to understand about Ra is its nature. Ra is
a sixth-density social memory complex. Since Earth is near the end of the
third-density cycle of evolution, this means that Ra is three evolutionary
cycles ahead of us. In other words, Ra’s present state of evolution is millions
of years in advance of Earthman’s. It is not surprising that Ra had difficulty
communicating with Earthman 11,000 years ago. The same problem still
exists in our present “enlightened” time."
"... one of my assets as a research associate is
my great gullibility. Almost anyone can play a joke on me because I do not
catch on quickly. I have a way of taking things as they come and accepting
them at face value and only afterwards analyzing what has occurred. This
gullibility is a vital factor in obtaining good results in paranormal research.
A desire for proof will inevitably lead to null results and voided
experiments. An open mind, one willing to be gullible, leads its possessor to
a kind of subjective and personal certainty which does not equal proof as it
cannot be systematically reproduced in others. However, this subjective
knowing is a central part of the spiritual evolution to which Ra speaks so
compellingly in this volume and which we have researched for many years
now."
