大方廣佛華嚴經疏 52.14

52.14

第九「不動心」下二門，明善法位中行。此門明外緣不動，後門明內心不捨。又此明心堅，後明深入皆是力義。今初十中，二及第九是思擇力，餘皆修習力。八中有十：一信，一生佛果故；二不雜，不信濁故；三淨，無煩惱故；四無細念故；五離所知垢故；六徹事源故；七向果位故；八自分堅故；九德無盡故；十緣不動故；十一證真如故。餘並相顯。二不捨深大心者，由不動故能窮理事，理深事廣故云深大。十句可知。

Ninth, the two gates beginning with the "unmoving mind" explain the practice within the station of wholesome dharmas. This gate explains being unmoved by external conditions; the subsequent gate explains not relinquishing the inner mind. Furthermore, this [gate] explains firmness of mind, while the subsequent explains deep entry—both being the meaning of power. In the first ten, the second and ninth are the power of thoughtful discrimination; the rest are all the power of cultivation and practice. In the eighth there are ten: 1. faith, because it gives birth to the fruit of buddhahood; 2. unmixed, because it is not turbid with disbelief; 3. purity, because it is without defilements; 4. because it is without subtle thoughts; 5. because it is free from the defilement of the knowable; 6. because it penetrates the source of phenomena; 7. because it tends toward the fruit station; 8. because one's own portion is firm; 9. because its virtues are inexhaustible; 10. because conditions do not move it; 11. because it directly realizes tathatā. The rest have obvious marks. Second, as for not relinquishing the profound and great mind: because of being unmoving, one can exhaust noumenon and phenomena; noumenon is profound and phenomena are vast, hence it is called profound and great. The ten clauses can be understood.
