I bet most of you have heard this saying before, "Do unto others as you would have them do unto you." A more layman's terms, treat others the way you want to be treated.
Notice it doesn't say expect others to treat you the way you want them to treat you. That is because, you/I are the source of inspiration other receive which motivates them, to a large part, to treat us the way we want to be treated because we have first treated them the way we want to be treated. This is also called leading by example.
I believe this sort of philosophy is not only applicable to people in there relations with others, but on a broader scale, countries and their relations to other countries.
If we lived by this saying, what could we expect from other countries, based upon our prior behavior towards them? We move our troops into their countries, bomb stuff, kill people and justify it via the "terrorist threat" excuses. So if that is the way we treat other countries, doesn't it seem logical that we could expect that sort of treatment from them?
I know we don't want wars, we want peace and harmony, well, the majority of the human race would probably agree with me on that. So, how to we establish a peaceful harmonious world? By treating others the way we want to be treated.
Personally, I enjoy being treated with love, respect, kindness, compassion and consideration, that's how I treat others. Might this sort of attitude be contagious? Yes, it could be, but each of us first must set the example in our own interactions with others.
One by one, we change the world in this way. I hope you will join with me and others by embodying the "Do unto others as you would have them do unto you." way of life.
