To paraphrase Sam Perry,  if you want to learn how to golf, you find a golf instructor and you can soon tell whether he’s a good golf instructor or not because you can measure how well he hits and how well you improve. But spirituality is next to impossible to measure. Therefore, until you practice with someone, you cannot tell if they are a good teacher. Mome “spiritual” leaders exude charm and charisma, not to mention they offer enlightenment and inner peace. You have to decide for yourself and listen to your own inner wisdom.
