瑜伽論記 7.38

7.38

自下第二解能修念，於中初開五門，次依門釋，後總結之。若准藏論等有六，謂數、隨、止、觀、還、淨也。今此初門當彼數也，餘門不同。

Next below, the second part explains the mindfulness capable of cultivation; therein it first opens five approaches, next explains according to the approaches, and finally summarizes them. According to treatises such as the Kośa, there are six: namely, counting, following, stopping, observing, returning, and purifying. Now this first approach corresponds to their counting; the other approaches are not identical.
