妙法蓮華經玄義 9.95

9.95

簡宗體者，有人言：宗即是體，體即是宗。今所不用。何者？宗致既是因果，因果即二體，非因非果，體即不二。體若是二，體即非體；體若不二，體即非宗。宗若不二，宗即非宗；宗若是二，宗即非體。云何而言：體即是宗，宗即是體？又，柱梁是屋之綱維，屋空是梁柱所取，不應以梁柱是屋空，屋空是梁柱。宗、體若一，其過如是。又，宗、體異者，則二法孤調，宗非顯體之宗，體非宗家之體。宗非顯體之宗，宗則邪倒無印；體非宗家之體，則體狹不周，離法性外，別有因果。宗體若異，其過如是。

In distinguishing the central purport and substance: some say that the central purport is itself the substance, and the substance is itself the central purport. We do not accept this now. Why? Since the central purport consists of cause and effect, cause and effect are two; the substance is neither cause nor effect, so the substance is non-dual. If the substance were two, the substance would not be the substance; if the substance were non-dual, the substance would not be the central purport. If the central purport were non-dual, the central purport would not be the central purport; if the central purport were two, the central purport would not be the substance. How then can one say: the substance is itself the central purport, and the central purport is itself the substance? Furthermore, pillars and beams are the structural framework of a house, and the empty space of the house is what is captured by the beams and pillars; one should not take the beams and pillars to be the empty space of the house, nor the empty space of the house to be the beams and pillars. If the central purport and the substance were identical, the fault would be like this. Furthermore, if the central purport and the substance were completely different, the two dharmas would be isolated and disconnected: the central purport would not be the central purport that reveals the substance, and the substance would not be the substance belonging to the central purport. If the central purport were not the central purport that reveals the substance, it would be errant, inverted, and unsealed; if the substance were not the substance belonging to the central purport, the substance would be narrow and not all-encompassing, and apart from the dharma-nature there would be separate causes and effects. If the central purport and the substance were different, the fault would be like this.
