" In Chinese Philosphy the concept of yin yang (often referred to in the west as yin and yang) is used to describe how seemingly disjunct or opposing forces are interconnected and interdependent in the natural world, giving rise to each other in turn.
Many natural dualities – e.g. dark and light, female and male, low and high – are cast in Chinese thought as yin yang.
According to the philosophy, yin and yang are complementary opposites within a greater whole. Everything has both yin and yang aspects, which constantly interact, never existing in absolute stasis. "
I think we often get so wrapped up in ourselves that we forget that we are all a part of a much larger picture. All interconnected and only as strong and healthy as the weakest and sickliest amongst us.
