12.106

基云：此進道勝行作有相行緣事相有差別故名世間，非涅槃樂之所纏縛故名不共，以體是無漏故以有相故亦名為共，有情所不能行故名不共，作緣事相故名共。

Ji states: This superior practice of advancing on the path performs practices with marks and takes the marks of conventional matters as its distinct objects, hence it is called 'worldly'; it is not fettered by the bliss of nirvāṇa, hence it is called 'unshared'. Because its intrinsic nature is taintless and yet possesses marks, it is also called 'shared'; because sentient beings are unable to practice it, it is called 'unshared'; because it takes conventional marks as its objects, it is called 'shared'.
