"He grows disenchanted with the ear... "He grows disenchanted with the nose... "He grows disenchanted with the tongue... "He grows disenchanted with the body... "He grows disenchanted with the intellect, disenchanted with ideas, disenchanted with consciousness at the intellect, disenchanted with contact at the intellect. And whatever there is that arises in dependence on contact at the intellect, experienced as pleasure, pain or neither-pleasure-nor-pain: He grows disenchanted with that too. Disenchanted, he becomes dispassionate. ...
"Furthermore, the monk remains focused on mental qualities in & of themselves with reference to the five clinging-aggregates...."Furthermore, the monk remains focused on mental qualities in & of themselves with reference to the sixfold internal & external sense media....unsustained by anything in the world.
"..."Therefore, monks, whatever isn't yours: Let go of it. Your letting go of it will be for your long-term welfare & happiness. And what isn't yours? Form (body) isn't yours: Let go of it. Your letting go of it will be for your long-term welfare & happiness. Feeling isn't yours... Perception... Thought fabrications... Consciousness isn't yours: Let go of it. Your letting go of it will be for your long-term welfare & happiness.http://www.accesstoinsight.org/tipitaka/mn/mn.022.than.html
