1At Sāvatthī. sn.ii.264 "Bhikkhus, just as it is easy for burglars to assail those families that have many women and few men, so too it is easy for nonhuman beings to assail a bhikkhu who has not developed and cultivated the liberation of mind by lovingkindness. [n.361] The simile is also at Vin II 256,16–18 and AN IV 278,22–25, but with a different application. Corehi kumbhatthenakehi is lit. "pot-thief bandits." Spk explains: Having entered the houses of others, having surveyed the scene by the light of a lamp, desiring to steal the belongings of others, they make a lamp in a jar (ghaṭe) and enter. Even mud-sprites (paṁsupisacakā) assail those devoid of development of lovingkindness, how much more then powerful nonhumans? Amanussa, lit. "nonhuman," usually denotes a malevolent spirit or demon.

"Just as it is difficult for burglars to assail those families that have few women and many men, so too it is difficult for nonhuman beings to assail a bhikkhu who has developed and cultivated the liberation of mind by lovingkindness.

"Therefore, bhikkhus, you should train yourselves thus: ‘We will develop and cultivate the liberation of mind by lovingkindness, make it our vehicle, make it our basis, stabilize it, exercise ourselves in it, and fully perfect it.’ Thus should you train yourselves."

1Sāvatthiyaṁ vihārati. "Seyyathāpi, bhikkhave, yāni kānici kulāni bahutthikāni appapurisāni tāni suppadhaṁsiyāni honti corehi kumbhatthenakehi; evameva kho, bhikkhave, yassa kassaci bhikkhuno mettācetovimutti abhāvitā abahulīkatā so suppadhaṁsiyo hoti amanussehi.

Seyyathāpi, bhikkhave, yāni kānici kulāni appitthikāni bahupurisāni tāni duppadhaṁsiyāni honti corehi kumbhatthenakehi; evameva kho, bhikkhave, yassa kassaci bhikkhuno mettācetovimutti bhāvitā bahulīkatā so duppadhaṁsiyo hoti amanussehi.

Tasmātiha, bhikkhave, evaṁ sikkhitabbaṁ: ‘mettā no cetovimutti bhāvitā bhavissati bahulīkatā yānīkatā vatthukatā anuṭṭhitā paricitā susamāraddhā’ti. Evañhi vo, bhikkhave, sikkhitabban"ti.

Tatiyaṁ.
