From a reclusive, Daoist hermit to a prominent scientist on the world stage, the belief in the basic rules of cause and effect tends to hold the same amount of water that hit Newton on top his head.
Sometimes the cause is already there, and there's no choice but to deal with the effects. Assuming we want the best for all, when choices do exist, we try to make the best choice to bring about the most desirable outcome—the karma of our dreams.
But, sometimes, the best choice isn’t clear. Alternate ways may produce equally satisfying results. Natural forces beyond our comprehension may work to shape momentary experiences, giving our futures deeper levels of direction and producing actions that favor equality and welfare for all. Sometimes. Maybe.
