Where there are consistent forces acting on a body (say, humanity, for instance), then there will be repetition of responses.
The key force acting upon humanity is ego -- selfishness and separateness.
So long as we ignore ego and let it run rampant, we will suffer repetition of the effects of ego.
The most insidious effect of ego is the power-hungry psychopath -- like the Rothschilds, Rockefellers, Bush's, Cheneys, Obamas and the like. They include many of the corporate leaders, especially the bankers in Wall Street and the very private Federal Reserve and other central banks, worldwide.
The only way to rise above this action-reaction-based mechanism is to turn to God and spirituality. We need to learn real forgiveness -- not the mammy-pamby fake forgiveness where people still can't "forget." Any attachment is not true forgiveness.
Dismissing ego is rising above the ties to physical existence. It's not as hard as it sounds, but it does require dedication and work.
