The nature of all things is the balancing of dualities.
To master one thing is to learn this act of balancing in the perspective of that thing. In visual art, this is the balancing between light and shadow, warm and cold, far and close, big and small, blurry and sharp, hard and soft. In music, this is the balancing between highs and lows, hard and soft, fast and slow, loud and quiet, many and few. In games this is the balancing between the fear and love, win and lose, hard and easy, suffering and pleasure. In a story, this is the balancing between fear and love, desire and obstacle, fulfillment and suffering, good and evil, life and death, love and hate, sad and happy. Every subject in the world can be understood through the act of balancing dualities.
