3.122

The commentary states: The names of the various Prajñā sūtras listed in the Sijiaoyi duplicate the general and the specific, making them difficult to distinguish. Here we merely designate them collectively under the Mahāprajñāpāramitā Sūtra. Ten sūtras—such as the Larger Prajñā, the Smaller Prajñā, the Heavenly King, the Mañjuśrī, and the Diamond Sūtras—are all texts that were retranslated or circulated independently from within the Mahāprajñāpāramitā; hence they are not listed here now. For 'Mahā' is simply the Larger Prajñā. Furthermore, the Shiqian states: 'In antiquity, the Prajñā was classified into five periods: first, the Mahā; second, the Diamond; third, the Heavenly King; fourth, the Guangzan; and fifth, the Benevolent Kings. This cannot yet be adopted. The Guangzan is merely the first part of the Larger Prajñā.' Examining this, we also know that the Guangzan should not be listed redundantly. The statement 'this cannot yet be adopted' is Jīngxī's overall refutation of the ancient teachers' error regarding the five periods.
