瑜伽師地論略纂 8.164

8.164

論云「由四念住增上力故，得無顛倒九種行相所攝正念，能攝九種行相心住，是名正念、正定」者，此中意，由四念住為因，生定心俱時九種念。九種念即與安住念等，與定九種同俱。以九種皆是定為助伴，定亦九種；以正念定為能攝，助伴以者為非所攝。此中，念攝相違，如《對法抄》會。

The treatise says: "Due to the predominant influence of the four smṛtyupasthānas, one attains right mindfulness subsumed under nine kinds of modes without inversion, capable of gathering the mind's dwelling in nine kinds of modes; this is called right mindfulness and right concentration." The meaning here is that with the four smṛtyupasthānas as cause, nine kinds of mindfulness arise simultaneously with the concentrated mind. The nine kinds of mindfulness are concurrent with settled mindfulness and so forth, co-occurring identically with the nine kinds of concentration. Because the nine kinds are all companions to concentration, concentration also has nine kinds; with right mindfulness and concentration being what can gather, the companions are what is gathered. Regarding the contradiction in mindfulness gathering, it is harmonized as in the Abhidharma Notes.
