I have read through the Law of One Ra material one time. I took away from it some new knowledge, but left what did not feel important to me behind. The terms STS (service to self) and STO (service to others) where popularized by individuals who have reviewed this material. That being said, all of the Eastern Religions have this theme of the Dark / Light, Negative / Positive playing off of each other for the sake of learning and accelerating the evolution of consciousness. The law of one was accurate when it described the scenario, however it is far from being the first to point it out.
If having the free will to choose the negative path where not part of this reality then people would not be able to get away with it for their whole lives. It is a greedy, materialistic, spiritually detached paradigm to live in and has a dead end where you have to go back and start over. Where as the positive path of light has no dead end and is a much more enjoyable.
Many on the negative path choose it because they do not belive in Karma. They think, "Screw it, I am going to do what ever I want, and unless someone catches me then I will be just fine". Then later on life takes a great big s--t on them and because of their paradigm they blame the world and become more selfish. This plays out over and over again in their life and sinks them further into victimitis and self pity every time it does.
Then they start over in a new life down the road and have to live out all of the bad Karma they developed in the last life. This once again puts them on the defensive, and if no one is around to give them the right guidence they end up repeating the same mistakes life after life after life.
As far as I know, off world entities where not responsible for this symbol.
However, they might have had something to do with this one
Chicken or the egg? Did Chinese farmers see the same kind of formation as above and copy it? Or did the ET's copy it from the Earthlings? It is a Koan
