摩訶止觀 9.3

9.3

Sixth, Contemplating the Realm of Dhyāna-Concentration: Chronic illness and traveling far are obstacles to dhyāna-concentration. The Lokasthiti-abhidharma says: 'Much disputation and reproof, and managing many affairs, are also obstacles to dhyāna-concentration; furthermore, much chanting and reciting is also an obstacle to dhyāna-concentration.' The Mañjuśrīparipṛcchā-bodhi-sūtra says: 'Dhyāna-concentration has thirty-six defilements.' Defilements are obstacles.
