And taiji means "the natural way" --standing erect and centered, being impartial and unbiased, neither lacking nor in excess, adhering to one position--in other words the way of the natural world, and the way of the human being. Or in short: moral cultivation, the very purpose of human life.
是「自然之道」﹘﹘立身中正、不偏不倚，無過不及，中土不離位，就是自然，就是作人，說穿了就是人生之道，就是修行。
