1.76

述曰：第六、不退中，「不退心」者，舉章門也。唯進無慮名不退心。古師云：凡夫有二習種，已前名外凡夫，地前三十心名內凡夫。今不退入於外凡也。「不起新長養諸見」者，伏分別惑故。「不起習因相似我人」者，漸伏俱生故。雖入三界業中流轉，而亦行空位不退也。又解脫現行障，於第一中道境智合行，故行不退也。又於本性空，正念不退也。證空生解，言「空生觀智」也。「如如相續」，如是如是乘勝心入於不二。結云：常時於空生心，一乘純淨，此為「不退一道一照」也。

The commentary says: In the sixth [mind], that of non-retrogression, "the non-retrogressing mind" introduces the chapter section. Proceeding exclusively forward without wavering is called the non-retrogressing mind. An ancient master states: Ordinary beings possess two types of training-nature; prior [to this] they are termed external ordinary beings, whereas the thirty minds prior to the bhūmis are termed internal ordinary beings. Now, one does not regress into being an external ordinary being. "Does not give rise to newly cultivated views" means that one subdues conceptual afflictions. "Does not give rise to the habitual causes resembling a self or a person" means that one gradually subdues innate afflictions. Although one enters into transmigration within the karma of the three realms, one practices the position of emptiness and does not regress. Furthermore, because one is liberated from the obstacles of active manifestation and conjunctively practices the middle-path object and wisdom in the supreme sense, one's practice does not retrogress. Moreover, with respect to the emptiness of intrinsic nature, one's right mindfulness does not retrogress. Realizing emptiness gives rise to understanding, which is why it says "contemplative wisdom born of emptiness." "Continuously such-like" means that by progressively mounting the superior mind one enters into non-duality. It concludes by stating: Constantly giving rise to the mind directed toward emptiness, pure in the One Vehicle, this is "the non-retrogressing single path and single illumination."
