"Ask a Bhante" : #5 : How to Handle the Metaphysical Aspects of Buddhism as a Modern Person. 

Question from Reed :
How are we as rational modern people supposed to regard all this “supernatural” stuff, like gods and devas and other realms and rebirth and karma? Was belief in them considered important by the Buddha as a facet of the Path? Can one become a stream-enterer or even an arahant without belief in them?
