It is the idea that most humans are constantly toggling between the three roles of victim, hero, and perpetrator. Each carries a profit. The victims is pity. The hero's is praise. The perpetrators is power/control. The solution is taking full responsibility as mature men and women. A researcher I enjoy, Harald Kautz Vella, postulates that the dynamic is Satanic in nature. It keeps one's consciousness in a state of perpetual suffering. I've found it to be helpful in my continued process of awakening.
