金剛經纂要刊定記 4.335

4.335

不生等者。謂我生已盡，梵行已立，所作已辦，不受後有。然前三句，即是盡智，後句即是無生智。謂不向三界之中，受有苦身也。以世間因亡果喪，出世間因成果證故。

"Unborn, etc." refers to: "My births are exhausted, the brahma-conduct is established, what was to be done has been done, and I will experience no further existence." The first three phrases are the knowledge of exhaustion, and the last phrase is the knowledge of non-arising. This means not receiving a body of suffering in existence within the three realms, because worldly causes have perished and results have vanished, and transworldly causes have succeeded and results have been realized.
