[181] "Udāyī, there are these four individuals found existing in the world. Which four? Here, Udāyī, a certain individual is practicing for the abandoning of attachment (upadhi), for the relinquishment of attachment. As he is practicing for the abandoning of attachment, for the relinquishment of attachment, memories and thoughts (sarasaṅkappā) connected with attachment beset him. He tolerates them; he does not abandon them, does not dispel them, does not bring them to an end, does not obliterate them. This individual, Udāyī, I call 'fettered,' not 'detached.' For what reason? Because the diversity of faculties (indriya) in this individual is known to me.
"But here, Udāyī, a certain individual is practicing for the abandoning of attachment, for the relinquishment of attachment. As he is practicing for the abandoning of attachment, for the relinquishment of attachment, memories and thoughts connected with attachment beset him. He does not tolerate them; he abandons them, dispels them, brings them to an end, obliterates them. This individual too, Udāyī, I call 'fettered,' not 'detached.' For what reason? Because the diversity of faculties in this individual is known to me.
"But here, Udāyī, a certain individual is practicing for the abandoning of attachment, for the relinquishment of attachment. As he is practicing for the abandoning of attachment, for the relinquishment of attachment, at times, now and then, owing to a lapse of mindfulness (sati), memories and thoughts connected with attachment beset him. Slow, Udāyī, is the arising of his mindfulness; but then he swiftly abandons them, dispels them, brings them to an end, obliterates them. Just as, Udāyī, if a man were to let two or three drops of water fall onto an iron cauldron heated all day: slow, Udāyī, would be the falling of the water drops, but then they would swiftly come to exhaustion and be used up—even so, Udāyī, here a certain individual is practicing for the abandoning of attachment, for the relinquishment of attachment. As he is practicing for the abandoning of attachment, for the relinquishment of attachment, at times, now and then, owing to a lapse of mindfulness, memories and thoughts connected with attachment beset him. Slow, Udāyī, is the arising of his mindfulness; but then he swiftly abandons them, dispels them, brings them to an end, obliterates them. This individual too, Udāyī, I call 'fettered,' not 'detached.' For what reason? Because the diversity of faculties in this individual is known to me.
"But here, Udāyī, a certain individual, having understood thus: 'Attachment is the root of suffering (dukkha),' is without attachment, liberated in the destruction of attachment. This individual, Udāyī, I call 'detached,' not 'fettered.' For what reason? Because the diversity of faculties in this individual is known to me. These, Udāyī, are the four individuals found existing in the world."
