法華文句記 3.129

3.129

本引令同何須求異，況今但以三同例之。名同乃是從便來耳。如五佛引同十方，無不從頓開漸，無不令至一切種智，此八子名作四對釋者，但得觀心，餘三全無。

Originally, they were cited to demonstrate sameness—why must one seek differences? What is more, here they are only being analogized based on the three samenesses. Sameness of name is merely brought in for convenience. Just as the five buddhas are cited as being the same as those of the ten directions, in that none do not open the gradual from the sudden, and none do not lead [beings] to arrive at the knowledge of all aspects—if one explains the names of these eight sons as four pairs, one only attains the contemplation of mind, while the other three [siddhāntas] are entirely absent.
