金剛三昧經論 1.13

1.13

論曰：此下第二別序，即有四分：一威儀分、二說經分、三入定分、四重頌分。威儀分者，如經爾時尊者大眾圍繞故。說經分者，如經為諸大眾說大乘經等故。此經文勢似《法華》序，如彼文言：爾時世尊四眾圍繞，說大乘經名無量義。如彼論中判此經名，即為《法華經》之異目。彼意以為在前說故名為序分。今看此經文勢皆是經家序辭，以是准之應是別經，在前廣說，說已入定，從定起已，方說金剛三昧經也。說經宗後乃說經名，當知一味真實等名，是前所說廣經之目。如是二經大意雖同，文相即異。前所說者廣說法門為益當時，後所說者略攝法門為利末世。是故在前廣說，以為略經緣由。此說經分文相有二：先序經名、後歎經德。「若聞」已下是第二分。

The commentary says: Below this is the second, specific prologue, which comprises four parts:
First, the comportment part;
Second, the sūtra-preaching part;
Third, the entering-samādhi part;
Fourth, the verse-recapitulation part.
The comportment part is as the sūtra says: "At that time, the Venerable One was surrounded by a great assembly."
The sūtra-preaching part is as the sūtra says: "for the great assembly he preached a Mahāyāna sūtra," and so forth. The stylistic structure of this sūtra resembles the prologue of the *Lotus Sūtra*, as that text states: "At that time, the World-Honoured One was surrounded by the fourfold assembly, and preached a Mahāyāna sūtra named *Immeasurable Meanings*." In the commentary on that sūtra, it designates this sūtra-name as an alternative title for the *Lotus Sūtra*. Its meaning was that because it was preached previously, it is called the prologue section. Looking now at the stylistic structure of this sūtra, these are all the narrator's introductory words; inferring from this, it must be an independent sūtra that was preached extensively beforehand. Having preached it, he entered samādhi; rising from samādhi, he then preached the *Vajrasamādhi-sūtra*. After stating the thesis of the sūtra, he then speaks the name of the sūtra; one should know that the title *The Single Taste, the Real*, etc., is the title of the extensive sūtra preached previously. Although the general purports of these two sūtras are identical, their textual forms differ. The one preached previously extensively expounded the Dharma gate for the benefit of that time; the one preached subsequently concisely condensed the Dharma gate for the benefit of the latter age. Therefore, it was preached extensively beforehand as the cause and condition for the concise sūtra.
This sūtra-preaching part has two textual aspects: first, introducing the sūtra's name; second, praising the sūtra's virtues. From "If someone hears" onward is the second part.
