"[...] what is meant by the observation of the mind? Answer: The observation of the mind means to observe one’s own mind and to find the Ten Worlds within it. This is what is called observing the mind. For example, though we can see the six sense organs of other people, we cannot see our own. Only when we look into a clear mirror do we see, for the first time, that we are endowed with all six sense organs. Similarly, various sutras make reference here and there to the six paths and the four noble worlds [that constitute the Ten Worlds], but only in the clear mirror of the Lotus Sutra and of the Great Teacher T’ien-t’ai’s Great Concentration and Insight can one see one’s own Ten Worlds, hundred worlds and thousand factors, and three thousand realms in a single moment of life."
