四教義 3.6

3.6

四明圓教四門者，四門明入佛性第一義，一往與別教四門入第一義諦、見佛性、得常樂涅槃，名義是同，細尋意趣有異。問曰：以何相知異耶？答曰：分別有異，意乃多途。今略約圓教七義分別，即知別教四門與圓教四門有殊也。七義者：一若明一切法即真性實相，佛性、涅槃不可復滅而明四門者，即是圓教四門也；二若初心即開佛知見、圓照而辨四門者，即圓教四門也；三若明不思議、不斷煩惱圓入涅槃而辨四門者，即是圓教四門也；四若明圓行而辨四門者，即是圓教四門也；五若明圓位而辨四門者，即是圓教四門也；六若明圓體而辨四門者，即圓教四門也；七若明圓用而辨四門者，即是圓教四門也。

Fourth, explaining the four gates of the perfect teaching: The four gates explain entering the paramārtha of Buddha-nature; for the time being, in entering paramārtha-satya, seeing Buddha-nature, and attaining the permanently joyful nirvāṇa, their name and sense are identical to the four gates of the distinctive teaching, but if one examines their purport in detail, there are differences. Question: By what characteristics does one know the difference? Answer: There are differences in distinguishing them, and the points of import are indeed manifold. Now, briefly distinguishing them in terms of the seven meanings of the perfect teaching, one immediately knows that the four gates of the distinctive teaching differ from the four gates of the perfect teaching. As for the seven meanings: first, if one explains that all dharmas are identical to the true nature and real mark, and that Buddha-nature and nirvāṇa cannot be extinguished again, and so explains the four gates, these are the four gates of the perfect teaching; second, if from the initial mind one immediately opens the Buddha's knowledge and vision and universally illuminates, and so distinguishes the four gates, these are the four gates of the perfect teaching; third, if one explains the inconceivable and entering nirvāṇa perfectly without cutting off defilements, and so distinguishes the four gates, these are the four gates of the perfect teaching; fourth, if one distinguishes the four gates in terms of perfect practice, these are the four gates of the perfect teaching; fifth, if one distinguishes the four gates in terms of perfect stages, these are the four gates of the perfect teaching; sixth, if one distinguishes the four gates in terms of the perfect essence, these are the four gates of the perfect teaching; seventh, if one distinguishes the four gates in terms of perfect function, these are the four gates of the perfect teaching.
