The Discourse on Seclusion at Jīvaka's Mango Grove
161.
On one occasion the Blessed One was dwelling at Rājagaha in Jīvaka's Mango Grove.
There the Blessed One addressed the monks, etc.
"Devote yourselves to seclusion, monks.
For a monk in seclusion, monks, it becomes clear as it really is.
And what becomes clear as it really is?
It becomes clear as it really is that the eye is impermanent, it becomes clear as it really is that material forms are impermanent, it becomes clear as it really is that eye-consciousness is impermanent, it becomes clear as it really is that eye-contact is impermanent, whatever feeling arises with eye-contact as condition - whether pleasant or unpleasant or neither-unpleasant-nor-pleasant - that too it becomes clear as it really is is impermanent, etc.
It becomes clear as it really is that the mind is impermanent, mental phenomena...
Mind-consciousness...
Mind-contact...
Whatever feeling arises with mind-contact as condition - whether pleasant or unpleasant or neither-unpleasant-nor-pleasant - that too it becomes clear as it really is is impermanent.
Devote yourselves to seclusion, monks.
For a monk in seclusion, monks, it becomes clear as it really is."
