It is one of many materials (messages) sent to us from higher density beings/collective(Ra) through chanelling. This is in the early 80s but the books themselves were published early 90s. You will find there from the history of earth, some specific names, creation, ourpose and so forth, all the way to evil ruling this world. Whether you believe all that is a different matter but I must say some of their info is being proven nowadays. A very simple explanation for a very complex message.
