the above symbol is called Yin and Yang, which is used to describe how polar or seemingly contrary forces are interconnected and interdependent in the natural world, and how they give rise to each other in turn. Many natural dualities — e.g. dark and light, female and male, low and high, cold and hot — are thought of as manifestations of yin and yang, respectively (from Wikipedia, obviously).
but.... not many who knows what it's connection to a human, as an individual. a friend once told me, which i believed is so true that i loved this symbol so much, is that;
as good as a person can be, there will definitely be a dark side of him / her. even a tiny drop of darkness, (which presented by the white portion contains the black seed). and as bad as a person can be, there will be a goodness in him/her, although just a small part (which presented by the black contains the white seed). it's make human, a human. nobody's perfect.
so.... don't just judge a book by its cover.
