妙法蓮華經玄義 4.177

4.177

過菩薩地，則入佛地。用誓扶餘習，生閻浮提，八相成道。五相如三藏不殊，唯六成道樹下，得一念相應慧，與無生四諦理相應，斷一切煩惱習盡，具足大慈悲、十力、四無畏、十八不共法，一切功德，名之為佛。七、轉法輪，權智開三藏生滅四諦法輪，實智說摩訶衍無生四諦法輪，通教三乘人也。八、入涅槃相者，雙樹入無餘涅槃，薪盡火滅，留舍利，為一切天人福田也。是為通教共位，別為菩薩立此名位也。

Surpassing the bodhisattva stage, one then enters the Buddha stage. Using vows to sustain the remaining propensities, they are born in Jambudvīpa and accomplish the path through the eight marks. Five marks are not different from those of the tripiṭaka [teaching]; only the sixth, accomplishing the path beneath the tree, is attaining the wisdom corresponding to a single thought, which accords with the principle of the unproduced four truths, severing all afflictions and residual propensities entirely, fully endowing great compassion, the ten powers, four fearlessnesses, eighteen unshared dharmas, and all merits; this is named a buddha. Seventh, turning the Dharma wheel: with provisional wisdom they set in motion the tripiṭaka wheel of the four truths of arising and cessation; with real wisdom they teach the Mahāyāna wheel of the unproduced four truths, which is the shared teaching for the persons of the three vehicles. Eighth, the mark of entering nirvāṇa: between the twin trees they enter nirvāṇa without remainder, wood exhausted and fire extinguished, leaving relics to serve as a field of merit for all devas and humans. These are the shared stages of the shared teaching, specifically establishing these names and stages for the bodhisattva.
