般若心經略疏連珠記 1.33

1.33

「二就」下，二、析法喻，二：初、約所詮以指法。就上所詮義中，復取心字以喻能詮教勝。唯般若等是所詮之法，故不言所喻。復云：所詮是知實相觀照，非所喻也。獨將一十四行文字般若為所喻，故但言「所引之喻」，不言能喻。

From "Second, with respect to" downward is the second [part]: analyzing the dharma and the metaphor, which has two parts: first, pointing to the dharma based on what is expressed. Within the aforementioned expressed meaning, he again takes the word "heart" as a metaphor for the superiority of the teaching that expresses. Only prajñā and so on are the dharmas expressed, and therefore he does not speak of "that which is likened." Furthermore, he says: Being expressed, it is understood to be the true mark and contemplation, not that which is likened. Solely taking the fourteen lines of verbal prajñā as that which is likened, he only says "the metaphor adduced," and does not say "that which likens."
