肇論新疏 3.308

3.308

初二句許前。結使下，正明其漸，此明方便淨也。三乘之人皆以見前伏惑，登見道已始盡分別，思惟位中漸斷俱生。如是已歷乾慧乃至已辦及辟支佛、菩薩等地，方得無漏盡、無生智。

The first two sentences grant what was said before. From “afflictive bondages” onward, it directly clarifies the gradual; this explains purity through expedient means (upāya). Followers of the three vehicles all subdue delusion before the path of seeing; having ascended the path of seeing, they only then exhaust discriminative [afflictions], and in the stage of cultivation they gradually sever innate [afflictions]. Having thus traversed through dry wisdom up to the stage of “that which is to be done has been done,” as well as the stages of pratyekabuddhas and bodhisattvas, they only then obtain the outflow-free exhaustion and unarisen wisdom (anutpāda-jñāna).
