Upakkilesasutta 2.1

2.1

Evamevaṃ kho, bhikkhave, pañcime cittassa upakkilesā, yehi upakkilesehi upakkiliṭṭhaṃ cittaṃ na ceva mudu hoti na ca kammaniyaṃ na ca pabhassaraṃ pabhaṅgu ca na ca sammā samādhiyati āsavānaṃ khayāya.

In the same way, there are these five corruptions of the mind. When the mind is corrupted by these it’s not pliable, workable, or radiant. It’s brittle, and not rightly immersed in samādhi for the ending of defilements.
