妙法蓮華經玄義 2.4

2.4

復次觀心釋。若觀己心不具眾生心、佛心者，是體狹；具者是體廣。若己心不等佛心是位下；若等佛心是位高。若己心、眾生心、佛心，不即空、即假、即中者，是用短；即空、即假、即中者，是用長。復次，於一法界通達十法界六即位者，亦是體廣，亦是位高，亦是用長。初約十法界，是顯理一；次約五味，是約教一；次約觀心，是約行一；次約六即，是約人一。略示妙義竟。

Next is the explanation according to contemplation of mind. If, when contemplating one's own mind, it does not possess the minds of sentient beings and the mind of the Buddha, its substance is narrow; if it possesses them, its substance is broad. If one's own mind does not equal the Buddha's mind, its position is low; if it equals the Buddha's mind, its position is high. If one's own mind, the minds of sentient beings, and the Buddha's mind are not identical with the empty, identical with the provisional, and identical with the middle, their function is short; if they are identical with the empty, identical with the provisional, and identical with the middle, their function is long. Furthermore, to thoroughly penetrate within a single dharma realm the positions of the six identities across the ten dharma realms is also to be broad in substance, high in position, and long in function. First, treating the ten dharma realms reveals the oneness of principle; next, treating the five flavors is based on the oneness of teaching; next, treating the contemplation of mind is based on the oneness of practice; next, treating the six identities is based on the oneness of persons. This concludes the brief indication of the profound meaning.
