「別解脫律儀至別解脫律儀」者，此下破第七證。別解脫律儀無別體性，亦應准此。謂由近因等起思願力故，先立要期誓不作惡，能定遮防身、語惡業。於加行位熏思種已，至第三歸依或第三羯磨事究竟時，從前思種復更熏成七支思種念念增長，由斯故建立別解脫律儀，思種假立而無別體。

On "The prātimokṣa restraint ... the prātimokṣa restraint": From here below refutes the seventh proof. The prātimokṣa restraint lacks a separate substantial entity; it should also be understood in accordance with this. That is, by the force of the volition and aspiration of the proximate cause and origin, one previously sets a resolution and vows not to commit evil, which is able definitively to obstruct and prevent unwholesome bodily and vocal karma. Having perfumed the volition-seeds in the preparatory state, when the matter is completed at the third refuge or the third karmavācanā, from the previous volition-seed the volition-seeds of the seven limbs are further perfumed and increase from moment to moment. On this basis the prātimokṣa restraint is established; it is nominally designated based on volition-seeds, without a separate substantial entity.
