釋摩訶衍論 9.32

9.32

已說神呪門，次說誦經門。以何義故建立此門？謂為令增威德力故。此事云何？彼佛弟子以種種門對治時中，若不須此誦經門者，力難對故。若如是者誦何等經？謂八陀多經、魔頭陀經、婆鄔舍經等。誦此等經以為對門。以此義故立誦經門。

Having explained the approach of dhāraṇī mantras, next I shall explain the approach of sūtra recitation. For what reason is this approach established? It is to augment majestic spiritual power. How is this so? When those disciples of the Buddha apply antidotes through various approaches, if they did not require this approach of sūtra recitation, their power would be hard-pressed to counter [them]. If so, what sūtras are recited? Namely, the *Aṣṭa-dhātaka Sūtra*, the *Māradhūta Sūtra*, the *Pauśa Sūtra*, and so forth. Reciting these sūtras constitutes the approach of countering. For this reason the approach of sūtra recitation is established.
