七、念覺分。若修出世道時，善能覺了，常使定、慧均平。若心沈沒，當念用擇法、精進、喜等三覺分察起。若心浮動，當念用除、捨、定等三分攝故。念覺常在二盈之間，調和中適，是念覺分。

Seventh, the factor of awakening of mindfulness. When cultivating the supramundane path, being skilled in discerning and constantly making samādhi and wisdom balanced. If the mind sinks, one should mindfully apply the three factors of awakening—investigation of dharmas, vigor, and joy—to inspect and uplift it. If the mind is restless, one should mindfully apply the three factors—pliancy, equanimity, and samādhi—to restrain it. Mindfulness of awakening constantly resides between the two excesses, harmonizing them appropriately; this is the factor of awakening of mindfulness.
