華嚴經探玄記 16.24

16.24

初分相者，性有三種，謂理、行、果。起亦有三，謂理性得、了因顯、現名起。二行性，由待聞熏資發生果名起。三果性起者，謂此果性更無別體，即彼理行兼具修生，至果位時合為果性。應機化用名之為起。是故三位各性各起，故云性起。今此文中，正辨後一兼辨前二也。

First, differentiating characteristics: "Nature" has three kinds, namely principle, practice, and fruit. "Manifestation" (or "arising") also has three: (1) that the nature of principle is obtained and made manifest through revealing causes is called manifestation; (2) the nature of practice, because it relies on hearing and perfuming to nourish and generate the fruit, is called manifestation; (3) regarding the manifestation of the nature of the fruit, this fruit nature has no separate substance apart from them—it is precisely that principle and practice together possess what is generated through cultivation, which combine to become the fruit nature at the stage of the fruit. Responding to capacities and transforming functions is termed manifestation. Therefore, the three stages each have their own nature and manifestation, hence it is called "nature manifestation." Now, in this text, it properly discerns the latter one while simultaneously discerning the former two.
