I never thought I would learn one of the most valuable lessons about humanity from one of the greatest physicists to ever exist, but I am.
Maybe Newton's third law applies to more than just physics equations. "For every action there is an equal and opposite reaction." Physics was not my best subject in school, but if this is a so called "Law of Physics," doesn't that mean it applies to everything? I think so.
I guess what I'm saying is that we never know how our actions are going to effect the world. We can't know how, but we must know that they will. All we can do is wake up every morning and pray that God will use us in a way that will help those around us and be open to follow what he tells us. And if we do that, hopefully we will be able to widen "our circle of compassion to embrace all living creatures and the whole of nature in its beauty."
