“My country is the world, and my religion is to do good.” – Thomas Paine
It is not enough to do no harm; we should seek to do good. Sometimes it can be discouraging to carry this out, especially if we look around and see examples of those who seek only to serve themselves. It is almost as if everyone is out to better only themselves and could care less about others and how they fare. In Buddhism though, we learn that we should always strive to do good, not only for ourselves but for others as well. Considering not only if we will benefit personally from some act, we try to look into how it will benefit others.
