The Discourse on What is Difficult to Dispel
160.
"Monks, these five things, when arisen, are hard to dispel.
Which five?
Arisen lust is hard to dispel, arisen hate is hard to dispel, arisen delusion is hard to dispel, arisen inspiration is hard to dispel, arisen urge to travel is hard to dispel.
These, monks, are the five things, when arisen, that are hard to dispel."
The tenth.
