The Discourse on What is Born of Contact
326.
At Sāvatthī.
"Whatever, monks, desire and lust there is for feeling born of eye-contact, that is an impurity of the mind.
Whatever... for feeling born of ear-contact...
whatever... for feeling born of nose-contact...
whatever... for feeling born of tongue-contact...
whatever... for feeling born of body-contact...
whatever desire and lust there is for feeling born of mind-contact, that is an impurity of the mind.
When, monks, for a monk... etc.
for phenomena to be realised by direct knowledge."
The fifth.
