楞伽阿跋多羅寶經註解 3.46

3.46

"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.
