"He discerns, as it actually is present, that 'The eye is inconstant'...'Forms are inconstant'...'Eye-consciousness is inconstant'...'Eye-contact is inconstant'...'Whatever arises in dependence on eye-contact, experienced either as pleasure, as pain, or as neither-pleasure-nor-pain, that too is inconstant.'

"He discerns, as it actually is present, that 'The ear is inconstant'...'The nose is inconstant'...'The tongue is inconstant'...'The body is inconstant"...

"He discerns, as it actually is present, that 'The intellect is inconstant'...'Ideas are inconstant'...'Intellect-consciousness is inconstant'...'Intellect-contact is inconstant'...'Whatever arises in dependence on intellect-contact, experienced either as pleasure, as pain, or as neither-pleasure-nor-pain, that too is inconstant.'

"So develop concentration, monks. A concentrated monk discerns things as they actually are present."
