[239] Bhikkhus, here a bhikkhu dwells in dependence on a certain village … dwells in dependence on a certain town … dwells in dependence on a certain city … dwells in dependence on a certain country … dwells in dependence on a certain individual. As he dwells in dependence on that individual, unestablished mindfulness does not become established, the unconcentrated mind (citta) does not become concentrated, the unexhausted taints (āsava) do not come to exhaustion, and he does not attain the unattained supreme security from bondage (yogakkhema); and those requisites of life that are to be procured by one gone forth — robes, almsfood, lodging, and medicinal requisites for the sick — are obtained only with difficulty. Bhikkhus, that bhikkhu should reflect thus: 'I am dwelling in dependence on this individual. As I dwell in dependence on this individual, unestablished mindfulness does not become established, the unconcentrated mind does not become concentrated, the unexhausted taints do not come to exhaustion, and I do not attain the unattained supreme security from bondage; and those requisites of life that are to be procured by one gone forth — robes, almsfood, lodging, and medicinal requisites for the sick — are obtained only with difficulty.' Bhikkhus, that bhikkhu should depart from that individual without taking leave, whether in a portion of the night or a portion of the day; he should not follow him.
