大方廣佛華嚴經疏 37.15

37.15

今初，對治顛倒道，名四念處。四謂身、受、心、法。念謂念慧，身等為其念慧所安住處，故亦名念住。《瑜伽》云「若於此住即是身等，若由此住即是念慧。體實是慧，以慧觀守境，由念得住，與念相近，隣近名念。」《雜集》云「一切菩提分法，皆由五門而得建立：一所緣、二自體、三助伴、四修習、五修果，文或略無，義必須具。」

Now, the first: the path that counters delusions is called the four applications of mindfulness. The four are body, feelings, mind, and dharmas. 'Mindfulness' refers to mindfulness and wisdom; the body and so forth are the places where this mindfulness and wisdom abide, hence they are also called 'stations of mindfulness' (smṛtyupasthāna). The Yogācārabhūmi says: 'That in which one abides is the body and so forth; that by which one abides is mindfulness and wisdom. In its true essence it is wisdom; because wisdom observes and maintains the object, and through mindfulness one comes to abide, being proximate to mindfulness, it is called "mindfulness" by contiguity.' The Abhidharmasamuccaya-vyākhyā says: 'All dharmas that are factors of awakening are established through five gateways: 1. the objective referent, 2. the essence, 3. the associates, 4. the cultivation, and 5. the fruit of cultivation. Though the text may be brief and omit some, in meaning they must all be present.'
