仁王護國般若波羅蜜多經疏 3.314

3.314

解曰：言非證者，方便智故。非不證者，影像故。若依《本記》，真中有俗故云非證，俗中有真故非不證。一切遍學者，住此地中一無數劫，萬行莊嚴遍修學故。如《成實論》廣學異論遍知意故。如《善戒經》遍學五明諸論等故。又《華嚴》三十四、《十地論》第二三，廣明行矣。從此第二向一切智。

The commentary explains: Saying "neither realizing" is because of skill-in-means cognition. "Nor not realizing" is because of the reflected image. According to the Original Notes, because within the real there is the conventional, it says "neither realizing"; because within the conventional there is the real, it says "nor not realizing." "Universally study everything" means that residing in this stage for one incalculable eon, they universally study and train to adorn the myriad practices. Just as the Tattvasiddhi-śāstra broadly studies disparate treatises so as to know all intentions, and the Śīlasaṃyukta Sūtra speaks of universally studying the treatises on the five sciences and so forth. Furthermore, the thirty-fourth fascicle of the Avataṃsaka Sūtra and the second and third fascicles of the Daśabhūmika-śāstra broadly explain these practices. Hereafter, the second part is heading toward all-knowledge.
