Without giving up six things, O monks, will it not be possible to dwell practising body-contemplation on the body...feeling contemplation on feelings...mind contemplation on the mind...mind-object contemplation on mind objects. Which are these?
To be fond of activity; to be fond of talking; to be fond of
sleeping; to be fond of company; lack of sense control; immoderate eating.
