The Discourse on Visible Forms
323.
At Sāvatthī.
"Whatever, monks, desire and lust there is regarding visible forms, that is an impurity of the mind.
Whatever... regarding sounds...
whatever... regarding odours...
whatever... regarding flavours...
whatever... regarding tangibles...
whatever desire and lust there is regarding mental phenomena, that is an impurity of the mind.
When, monks, for a monk the impurity of the mind regarding these six states has been abandoned, his mind slants towards renunciation.
The mind developed through renunciation appears workable for phenomena to be realised by direct knowledge."
