Philosophy

There is yin and yang. Things always move to balance themselves. Positive/negative. Dark/light. Even in winter, when there is so much more dark than light, there will soon enough come summer to tip the balance back and even it out. There is diffusion. There is osmosis. Things always move from an area of greater concentration to an area of lesser concentration.
And so, keeping this philosophical observation in mind, I believe that although there IS evil in the world, there is an equal amount of good. In fact, I would bet, based upon science and history, that there is EXACTLY the same amount of good and evil. For every man that would kill a man as soon as look at him, there is another who would lay down his life for a stranger.
And so,the lesson is, believe in yin and yang. Believe that there is balance in the universe. And in believing this, know that you can choose to focus on the good, the light, the positive. You can choose happiness over sorrow. Without pain there is no pleasure. Embrace it all in acceptance, and feel the joy of life.
