Do not be confused by people who try to disprove the existence of objects of faith like reincarnation or karma by simply labeling them as nonexistent.
-Lama Zopa Rinpoche
Lama Zopa Rinpoche addresses how some people try to disprove the existence of reincarnation and other objects of Buddhist faith by labeling them as false views or heresy. Rinpoche demonstrates how labeling something cannot make the labeled phenomena function according to that label. In a similar way, we should not be confused by people who label our objects of faith as nonexistent. Instead we should rely on our faith and apply our wisdom in meditation to experience their functional phenomenal existence. Rinpoche gave these teachings during a lamrim course at Maitreya Instituut, Emst, in August 1990.
