楞伽阿跋多羅寶經註解 3.46

3.46

謂古先聖道者，即先佛所證性德之法也。如金銀等性者，喻本住法性如金之堅剛，非鍛鍊所得。法界常住亦復如是，所謂有佛無佛性相常住。又言法界常住者，結本住法也。又曰「如趣彼城道」等，此兼喻自得、本住二法歸乎一致。所謂平坦正道者，本住法也；士夫入城受樂者，自得法也。以其本有正道，故得隨之而入，入已安之，皆非外物。言此二法本有之性非言思所及，所以五十年中一大藏教不說一字者，非曰不說，蓋以言遣言，三世諸佛其歸一揆也。偈頌文顯，不釋。

"The ancient path of the sages" refers to the dharma of natural virtue realized by past Buddhas. "Like the nature of gold, silver, and the like" illustrates that the nature of the originally abiding dharma is like the hardness and solidity of gold, which is not obtained through smelting. That the dharmadhātu ever abides is also like this—namely, whether there are Buddhas or no Buddhas, its nature and characteristics ever abide. Furthermore, saying that "the dharmadhātu ever abides" concludes [the discussion of] the originally abiding dharma. Also, saying "just like the road leading to that city" and so forth combines the metaphors of the two dharmas—what is realized by oneself and what originally abides—showing they return to unity. What is called the "even and straight road" is the originally abiding dharma; the "man entering the city and experiencing pleasure" is the dharma realized by oneself. Because there is an originally existing straight road, he can follow it and enter; once entered, he rests in it, neither of which are external things. This indicates that the originally existing nature of these two dharmas is beyond words and thought. Therefore, throughout fifty years of the great canon of teachings, not a single word was spoken—not that he truly did not speak, but that he used words to dispel words; the Buddhas of the three periods return to the same principle. The text of the verse is clear and will not be explained.
