法華文句記 7.187

7.187

雖難而易，時眾聞說如來二智，知佛法身恒思大小，秖恐領教未必盡善，故佛以二教二智述其齊教無差謬也。又齊教述尚自不虛，驗知探領亦應非謬。

Although difficult, it is easy: the assembly at that time, hearing the exposition of the Tathāgata's two wisdoms, knew that the Buddha's dharmakāya constantly contemplates the great and small; they only feared that his understanding of the teaching might not be completely perfect. Therefore, the Buddha, by means of the two teachings and two wisdoms, recounted that his [comprehension] equal to the teaching was free of error. Furthermore, since the account of what is equal to the teaching is itself not untrue, it proves that his probing understanding must also be free of error.
