Daoism views the universe as being in a natural balance of opposing forces called yin and yang. Divination practices have been part of Daoism, which involve attempting to predict the future or gain hidden knowledge through supernatural means. Confucius was an ancient Chinese philosopher who taught about virtue, righteousness, and proper social relationships. He emphasized ethics, correctness of social relationships, justice, and sincerity. As a quote attributed to Confucius states "By three methods we may learn wisdom: First, by reflection, which is noblest; Second, by imitation, which is easiest; and third by experience, which is the bitterest."
