4.23

論。無明亦爾至非心智滅　釋曰。此法合也。無明亦爾依心體動者。顯離於心不能自動。若心體滅眾生等者。謂境滅時心體若滅。則無明風無所依動其業轉現。眾生根體無依止故亦便斷滅。以體不滅心得相續者。以境滅時體不滅故不相應。心而得相續者。以境滅時體不。以無明滅故境界滅。非境界滅故無明滅。由是義故。境界滅時無明動心三細相續。此顯相應心滅之義。答初問也。唯癡滅故心相隨滅等者。以無明盡時業等動相盡。非靜心體而亦隨滅。此顯不相應心滅之義。答後問也。此中癡者即是無明。言心起者即真心性。前顯一識生滅不生滅義。故說覺不覺。今顯一心有體相義故說癡及智。名義雖異而體無別。

[Treatise:] Avidyā is also like this: [depending on the mental substance it moves. If the mental substance ceases, sentient beings would be severed and have nowhere to depend; because the substance does not cease, the mind can continue. Only when delusion ceases does the mental characteristic cease along with it, not the mind-cognition ceasing.]
[Commentary:] This is the application of the simile to the doctrine. 'Avidyā is also like this: depending on the mental substance it moves' reveals that apart from the mind it cannot move by itself. 'If the mental substance ceases, sentient beings,' and so forth, means: when objects cease, if the mental substance were to cease, then the wind of avidyā would have nowhere to depend upon to move; the root-substance of sentient beings—karmic, evolving, and manifesting [consciousnesses]—having nowhere to abide, would then also be severed and cease. 'Because the substance does not cease, the mind can continue' means: because when objects cease the substance does not cease, the non-corresponding mind can continue. Because avidyā ceases, objects cease; it is not because objects cease that avidyā ceases. By this meaning, when objects cease, the mind stirred by avidyā and the three subtleties continue. This reveals the meaning of the cessation of the corresponding mind, answering the first question. 'Only when delusion ceases does the mental characteristic cease along with it,' and so forth, means: when avidyā is exhausted, the moving characteristics such as karma are exhausted; it is not that the tranquil mental substance also ceases along with them. This reveals the meaning of the cessation of the non-corresponding mind, answering the latter question. Here, 'delusion' is avidyā. The phrase 'mind arising' is the nature of the true mind. Previously, to reveal the meaning of arising-and-ceasing and non-arising-and-ceasing in the one consciousness, awakening and non-awakening were spoken of. Now, to reveal the meaning of substance and characteristic within the one mind, delusion and cognition are spoken of. Although the terms and meanings differ, their substance is not distinct.
