The Discourse on the Internal Past as Impermanent
186.
"The eye, monks, is impermanent, past, etc.
the tongue is impermanent, past, etc.
the mind is impermanent, past.
Seeing thus, monks, a learned noble disciple becomes disenchanted with the eye, etc.
becomes disenchanted with the tongue, etc.
becomes disenchanted with the mind.
Being disenchanted, he becomes dispassionate;
through dispassion, he becomes liberated;
when liberated, there is the knowledge: 'Liberated.'
He understands: 'Birth is eliminated, the holy life has been lived, what had to be done has been done, there is no more coming back to any state of being.'"
