Confucius said, At fifty, one knows the destiny of heaven. Zhu Xi's note: The destiny of Heaven, that is, the person who bestows gifts upon the popularity of the tao of heaven, is the food. To know this is to know extremely well, and not to be confused is not enough. Zhu Xi said the destiny of Heaven from the way of heaven, and from the perspective of humanity, knowing the destiny of Heaven is to know the limitations of one's own life, know what can be done or not done, and do what is not done, because this knowing not only produces a profound change in the behavior of one's own will, but also forms a great transformation in the relationship between oneself and the world.
