4.18

「陽上陰下」者，如天地也，此是世俗所用。「右陽」下，正明佛法表對之意。右陽左陰，如前記。「欲將」等者，陰表定、陽表散，散即定障也，故以陰上陽下。「世俗既有威儀」者，即左手壓右手為世俗威儀也。「此即」下，示所表麁獷，即七支愆過也。「自權而顯實」者，自，從也。先安右手居下，如先施權。後以左手置上，如後顯實。「此戒」等者，於十人中，唯約人明慧，復須甄別。分段中，七人是權，一人是實；變易中，一權一實。慧既不等，戒定自殊。

Regarding "yang above and yin below," it is like heaven and earth; this is what is used in secular custom. From "the right is yang" downward, it directly explains the meaning of symbolic representation in the Buddhadharma. The right is yang and the left is yin, as noted previously. Regarding "wishing to take...," and so forth, yin represents concentration, and yang represents distraction; distraction is an obstacle to concentration; therefore, yin is placed above and yang below. Regarding "since secular custom has deportment," placing the left hand over the right hand is the secular deportment. From "this is..." downward, it shows that what is represented is coarse and rough—that is, the transgressions of the seven branches [of karma]. Regarding "from the provisional, displaying the real," zi (自) means "from." First placing the right hand below is like first setting forth the provisional; afterward placing the left hand above is like afterward displaying the real. Regarding "these precepts," and so on, among the ten kinds of persons, explaining wisdom is done only in terms of the persons, and further discrimination is needed. Within the stage of portioned [birth and death], seven persons are provisional and one person is real; within the stage of transformational [birth and death], one is provisional and one is real. Since wisdom is not equal, precepts and concentration are naturally distinct.
