Ajahn Viradhammo. Tisarana Non-Residential Retreat 2013 (Eleventh Talk). We deal with thought by changing unskillful perceptions into skillful perceptions. We are trying to figure out how to balance the mind, asking ourselves: “what does the mind need right now?” It might be asubha contemplation, metta meditation, contemplation of space or some other meditation object.
Other questions asked: Is contemplation analytical and therefore not meditation? How does desirelessness relate to meditation?
