The Eternal Mirror
Ko means “ancient” or “eternal” and kyo means “mirror,” so kokyo means “the eternal mirror.” And what “the eternal mirror” means is the question. In this chapter Master Dogen quoted Master Seppo Gison’s words “When a foreigner comes in front of the mirror, the mirror reflects the foreigner.” From these words we can understand the eternal mirror as a symbol of some human mental faculty. The eternal mirror suggests the importance of reflection, so we can suppose that the eternal mirror is a symbol of the intuitional faculty. In Buddhist philosophy, the intuition is called prajna, or real wisdom. Real wisdom in Buddhism means our human intuitional faculty on which all our decisions are based. Buddhism esteems this real wisdom more than reason or sense-perception. Our real wisdom is the basis for our decisions, and our decisions decide our life, so we can say that our real wisdom decides the course of our life. For this reason, it is very natural for Master Dogen to explain the eternal mirror. At the same time, we must find another meaning of the eternal mirror, because Master Dogen also quoted other words of Master Seppo Gison, “Every monkey has the eternal mirror on its back.” Therefore we can think that the eternal mirror means not only human real wisdom, but also some intuitional faculty of animals. So we must widen the meaning of the eternal mirror, and understand it as a symbol of the intuitional faculty which both human beings and animals have. Furthermore Master Seppo Gison said, “When the world is ten feet wide, the eternal mirror is ten feet wide. When the world is one foot wide, the eternal mirror is one foot wide.” These words suggest the eternal mirror is the world itself. So we can say that the eternal mirror is not only a symbol of an individual faculty but is also something universal. From ancient times Buddhists have discussed the eternal mirror. In this chapter Master Dogen explains the meaning of the eternal mirror in Buddhism, quoting the words of ancient Buddhist masters.
