[462] "Anuruddhas, as I dwelt diligent, ardent, and resolute, I perceived both light and the vision of forms. But before long that light of mine vanished, and the vision of forms. Then, Anuruddhas, it occurred to me: 'What now is the cause, what is the condition, whereby my light vanishes, and the vision of forms?' Then, Anuruddhas, it occurred to me: 'Excessive meditation upon forms (atinijjhāyitattaṃ rūpānaṃ) arose in me, and on account of that excessive meditation upon forms my concentration (samādhi) fell away. When concentration has fallen away, the light vanishes, and the vision of forms. I shall so act that neither doubt shall arise in me again, nor non-attention (amanasikāra), nor dullness and drowsiness, nor terror (chambhitatta), nor elation (ubbila), nor gross inertia (duṭṭhulla), nor excessively aroused energy, nor overly slack energy, nor longing (abhijappā), nor perception of diversity (nānattasaññā), nor excessive meditation upon forms.'"
