2.107

并內界十二者，眼等五界及七心界，名為十二。非直法界一分為根，並內界十二為根體也。且眼等五界攝眼等五根也，七心界攝意根也。意界、意識界此二攝後三無漏根中一分也。言一分者，三無漏根，九根為體，於九根中唯攝意根，故言一分。女根、男根即是身根一分所攝，如後當辨。義准所餘色等五界，法界一分，皆體非根。

Together with the twelve internal dhātus: the five dhātus of the eye and so on and the seven mind dhātus are called twelve. Not only is one portion of the dharmadhātu an indriya, but together with it, the twelve internal dhātus are the substance of indriyas. The five dhātus of the eye and so on comprise the five indriyas of the eye and so on, while the seven mind dhātus comprise the mind indriya. The manodhātu and manovijñānadhātu comprise one portion of the last three untainted indriyas. 'One portion' means that the three untainted indriyas have nine indriyas as their substance; among these nine indriyas, they comprise only the mind indriya, hence it is said 'one portion'. The female indriya and the male indriya are comprised within one portion of the body indriya, as will be distinguished later. By implication, the remaining five dhātus of rūpa and so on, as well as one portion of the dharmadhātu, are all in substance not indriyas.
