11.116

景云：言於世間者，即觀苦也。於世間集，於世間滅者，即觀集滅也。於能往趣世間集行者，此觀受也。因受生愛，愛是集體受為往趣，集之行也，餘處但作七觀不觀於受。於能往趣世間滅行者，此觀道也。愛味者，重觀於集。過患者，重觀於苦。及出離者，重觀於滅，略不重觀於道，以能觀心即是道故，以集是生死之本所以三度觀之。

'Jing says: Speaking of 'regarding the world' is precisely contemplating suffering. 'Regarding the origin of the world' and 'regarding the cessation of the world' are precisely contemplating origin and cessation. 'Regarding the practice leading to the origin of the world' is contemplating feeling (vedanā). Conditioned by feeling, craving arises; craving is the essence of origin, and feeling is the practice of leading to origin; elsewhere they only perform seven contemplations and do not contemplate feeling. 'Regarding the practice leading to the cessation of the world' is contemplating the path. 'Gratification' is contemplating origin again. 'Danger' is contemplating suffering again. 'And departure' is contemplating cessation again. It omits contemplating the path again, because the contemplating mind is itself the path. Because origin is the root of saṃsāra, it is contemplated three times.
