In our society, pervading all cultures and religions, we have the dualistic concept of good and evil, right and wrong, righteousness and unrighteousness, light and dark. However, under those terms and creeds that we have been provided, there always seems to be a subjective interpretation of how a circumstance can be considered and what category such events should fall into. In my search to separate and categories to help my ego mind understand the nature of these concepts, the Law of One material seems to have the best way of grouping such duality.
Under the Law of One published in the early 1980's, we are currently going through a harvesting process (post 2012) where individuals are harvested based on such dualistic concepts. Provided that the Earth has moved from a free-will solar plexus (3rd density) based planet into a compassionate loving heart based planet (4th density), humans are choosing whether to continue in 3rd density or move into 4th density. The choice is based on the dualistic concept, not of good and evil, but of either "service to self" or "service to others". The service to self concept would be in the negative, where an entity is more intrigued with dominating and manipulating other entities. The service to others concept is a much more compassionate viewing others on an equal footing. Hence, service to self is "separation", whereas, service to others is "unification".
Before we assess which choice is good or bad, the Law of One material makes it clear that both options are necessary and are of service to the infinite one. Service to self and service to others are both expressions of the infinite, and the infinite would not be infinite if one option ceased to exist. It is through both options that the infinite can express itself in different factions and aspects of creation. So yes, even through the manipulative service to self aspect can the infinite continue to express itself for the infinite is "all that is".
Returning to the Ramayana and recognizing the purpose of Ravana, a catalyst for Rama's journey to become a hero, do I have a better sense of this duality and the necessity for both to balance each other. In a school of spirituality, the best example that I can give is Harry Potter, where everyone takes the same curriculum and learns magick (siddhis/boons). Although everyone is provided with such education, you are still under the free-will concept of what you are able to do with such knowledge. Much like Harry Potter was trying to do good and his opponent was simply power hungry, we have that similar situation in the Ramayana. Rama was simply attempting to maintain the status quo, to have a blessed kingdom in service to his people, where Ravana was self-interested looking to manipulate and control. Hence, we have a battle between service to others and service to self.
