肇論 1.71

1.71

有名曰：涅槃既絕圖度之域，則超六境之外，不出不在而玄道獨存。斯則窮理盡性究竟之道，妙一無差。理其然矣。而《放光》云：「三乘之道，皆因無為而有差別。」佛言：「我昔為菩薩時，名曰儒童。於然燈佛所，已入涅槃。」儒童菩薩時於七住初獲無生忍，進修三位。若涅槃一也，則不應有三；如其有三，則非究竟。究竟之道，而有升降之殊。眾經異說，何以取中耶？

The Named One said: "Since nirvāṇa cuts off the realm of conceptual measurement, it transcends outside the six sense objects; neither transcending nor abiding, the mysterious path exists alone. This, then, is the ultimate path that exhausts principle and fulfills nature, wondrously one and without differentiation. In principle it should be so. Yet the Fangguang jing says: 'The paths of the triyāna all possess differences based on the unconditioned.' The Buddha said: 'Formerly, when I was a bodhisattva named Māṇava, I already entered nirvāṇa in the presence of Dīpaṃkara Buddha.' At the time of the bodhisattva Māṇava, upon the seventh stage he first attained the forbearance of non-arising, and then advanced to cultivate three stages. If nirvāṇa is one, there should not be three; if there are three, it is not ultimate. If it is the ultimate path, yet there are differences of ascending and descending. Among the different teachings of the various sūtras, how does one determine the center?"
