23.205

長行釋中，初解道不同分，言若趣苦集行者，業與煩惱。若趣苦滅行者，無漏聖道，名性不同。即此趣滅轉行，或有有為共相轉者，觀無常。或有有為無為共相行轉者，通觀諸法為空無我。當知若諸有為共相行相，彼望道果，名不同分者，不觀無為果故。若有為無為共相行，彼望道果，亦名同分者，無我理通涅槃，亦常無我故。

In the prose explanation, it first explains the dissimilar parts of paths. Regarding "practices leading toward the origin of suffering": karma and afflictions. "Practices leading toward the cessation of suffering": the taintless noble path; these are called different in nature. As for these very practices directed toward cessation, some operate with the common characteristics of conditioned phenomena, which is observing impermanence. Some operate with the common characteristics of both conditioned and unconditioned phenomena, which comprehensively observes all phenomena as empty and non-self. One should know that if they have the mode of practice of the common characteristics of conditioned phenomena, with respect to the fruit of the path, they are called dissimilar parts, because they do not observe the unconditioned fruit. If they have the practice of the common characteristics of conditioned and unconditioned phenomena, with respect to the fruit of the path, they are also called similar parts, because the principle of non-self extends to nirvāṇa, which is also constantly non-self.
