7.526

此四念住，總約諸蘊說名壞緣念住等者，此說總緣五蘊名雜緣法念住。差別修身念住者，但取青等顯色長等形色身業表色，於三品而起勝解故，立身念住。泰云：若四念住已得成熟總緣諸蘊名壞緣念住，若方便時但取色相唯身念住。

Regarding the passage, "these four applications of mindfulness, explained with respect to all the aggregates collectively, are called the application of mindfulness with corrupting objects," and so forth: this states that taking the five aggregates collectively as an object is called the application of mindfulness on phenomena with mixed objects. For the distinct cultivation of the application of mindfulness on the body, one merely grasps manifest forms such as blue, shaped forms such as long, and bodily action indicative forms, and by generating resolute intention with respect to the three grades, the application of mindfulness on the body is established. Tai says: if the four applications of mindfulness have already matured, taking all aggregates collectively as an object is called the application of mindfulness with corrupting objects; when in the preparatory stage, merely grasping the characteristic of forms is purely the application of mindfulness on the body.
