十二門論宗致義記 1.22

1.22

四者、此非一與非異亦非一，是故即非一之非異與即非異之非一，義不雜故而非一也。謂不異中之二、不異二之中，雖義融通，理不雜故。非中非二、具足中二，是謂中邊無障無礙，思之可見。

Fourth, this non-identity and non-difference are also not identical. Therefore, the non-difference that is identical with non-identity and the non-identity that is identical with non-difference are non-identical because their meanings are not confounded. That is to say, the two within the undifferentiated and the middle within the undifferentiated two, though their meanings thoroughly blend, do not have their principles confounded. Neither middle nor two, yet fully possessing both middle and two—this is termed the freedom from impediment and obstruction between middle and extremes; reflecting upon it, this can be seen.
