63.4

Regarding the commentary's phrase "moreover, although within a single kṣaṇa" and so on: the fifth [treats] their status in stages. That is to say, although the path of seeing is swift and possesses sixteen moments of mind, in principle, within a single kṣaṇa the seven factors arise together; their functions differ, so they cannot be called one. It is like pounding, sifting, and blending seven kinds of incense: burned as a grain of hemp, the seven fragrances release simultaneously. From "mindfulness eliminates erroneous thoughts" onward, it individually indicates their distinct characteristics.
