Five meanings that are related to mind are enumerated by Chih-i. …

With regard to the mind that contains the meaning “slight emanation” (Hsin-han Wei-la), this means that it is one’s mind that leads one to gradually progress to reach the final goal of realizing truth. Mind as “slight emanation” is also related by Chih-i to words, practice and principle. In terms of the mind that is related to slight emanation of words, this means that when mind is unimpeded, words are initiated. In terms of the mind that is related to slight emanation of practice, this means that when one has initially brought forth a resolve to the Bodhi-mind, one’s practice is weak. Later, one’s practice gradually gets established. In terms of the mind that is related to slight emanation of principle, this means that although a person cannot perceive the principle when he just starts contemplating mind, as he continues to cultivate, he is able to eventually reach truth.
