2.152

A sūtra says: 'It is like a red-hot glowing iron pellet wrapped in kalpa-cotton: does the cotton catch fire quickly or not?' The monks said, 'It catches fire quickly.' The Buddha said, 'A foolish person dwells relying on a settlement, does not guard the mind of precepts well, and lacks right mindfulness. With the fire of desire burning his heart, he abandons the precepts and returns to lay life. Therefore, all of you should guard the sense-doors.'
