摩訶止觀 9.119

9.119

又諸佛皆於此觀而般涅槃。若約鈍根，無明滅乃至老死滅，正習俱盡者，是三藏佛有餘、無餘涅槃；約即空觀無明滅乃至老死滅，是通教佛有餘無餘涅槃；約因緣假名中道觀無明滅乃至老死滅，是別教佛常樂我淨涅槃；約十二因緣，三道即三佛性，亦三涅槃，涅槃名諸佛法界，是圓教遮那佛四德涅槃。此是同居土示涅槃相，有四種，出《像法決疑經》。方便、實報二土，成道、轉法輪、入涅槃亦應可解。是名「十二因緣攝法義」（云云）。

Furthermore, all Buddhas enter parinirvāṇa based on this contemplation. In terms of dull faculties, the cessation of ignorance up to the cessation of aging and death, where both active defilements and residual habits are exhausted, is the Tripiṭaka Buddha's nirvāṇa with remainder and without remainder; in terms of the contemplation of identity with emptiness, the cessation of ignorance up to the cessation of aging and death is the shared teaching Buddha's nirvāṇa with remainder and without remainder; in terms of the middle way contemplation of dependent origination as provisional designation, the cessation of ignorance up to the cessation of aging and death is the distinctive teaching Buddha's nirvāṇa of permanence, bliss, self, and purity; in terms of the twelve links of dependent origination where the three paths are identical to the three Buddha-natures and also the three nirvāṇas, nirvāṇa being called the dharmadhātu of all Buddhas, this is the perfect teaching [Vairo]cana Buddha's nirvāṇa of the four virtues. These are the four kinds of manifestations of nirvāṇa in the realm of shared dwelling, appearing in the Xiangfa jueyi jing. In the two realms of expedient means and true reward, the attainment of the Way, turning the Dharma wheel, and entering nirvāṇa should likewise be understood. This is called "the doctrinal meaning of the twelve links of dependent origination subsuming phenomena," and so forth.
