金光明經文句記 4.53

4.53

二、諸雙非修圓空。若邪小及別教門，雖曰雙非皆成取相，皆須修於三諦俱空，名畢竟空。由諸雙非及諸空句非究竟道，是九界法，是故皆須修於圓教空中妙觀，歸祕密藏。

Second, the various 'neither' [phrases] cultivate perfect emptiness. If in the gates of the wrong, the Small [Vehicle], or the Separate Teaching, although called 'neither,' they all become grasping at marks; all must cultivate the emptiness of all three truths, which is called ultimate emptiness. Because the various 'neither' and 'emptiness' phrases are not the ultimate path and are dharmas of the nine realms, one must therefore cultivate the wondrous contemplation of emptiness and the middle of the Perfect Teaching to return to the secret treasury.
