四明尊者教行錄 3.60

3.60

答：斯乃以藏助於衍也。且彼經云：普明王依過去七佛之法，請百法師，一日二時講般若波羅蜜八千億偈竟。第一法師為王說偈，即無常等四，豈非正宣般若、傍演無常？所以然者，普明既為斑足所捉，將赴其死，恐王戀著身命國土，是故偈意皆勸捨身及國土等。至聞偈畢，諸王皆證三門空定，還是衍門得益之相耳。故今家明通等三教，俱用藏教而為助道，即此意也。

Answer: This is using the Tripiṭaka to assist the Mahāyāna. Moreover, that sūtra states: King Puming, relying on the Dharma of the seven past Buddhas, invited one hundred Dharma masters, who expounded the Prajñāpāramitā in eight hundred billion verses twice a day. When this was completed, the first Dharma master spoke verses for the king, which were precisely the four on impermanence and the rest. Is this not a primary proclamation of Prajñā with a secondary elaboration on impermanence? The reason for this is that Puming had been captured by Kalmāṣapāda and was about to face death; fearing that the king harbored lingering attachment to his physical life and realm, the import of the verses urged renunciation of body, realm, and so forth. When they finished hearing the verses, all the kings realized the empty absorption of the three gates—this is still the mark of gaining benefit through the Mahāyāna gate. Thus our school clarifies that the three teachings, such as the shared, all use the Tripiṭaka teaching as an aid to the path—this is precisely what it means.
