佛說盂蘭盆經疏 2.9

2.9

Second, the initiating introduction (in six parts). As for 'initiating': since this sūtra takes filial compliance and the relief of suffering as its central doctrine, it relies on the occasion of rescuing the mother to initiate it. The text is divided into six: 1. Maudgalyāyana's attainment of the Way; 2. Knowing kindness and wishing to repay it; 3. Yearning and searching everywhere; 4. Seeing her location; 5. Weeping bitterly and going to rescue her; 6. Evil habits manifesting.
