Once while he was still young, Rinpoche was approached by an old
man who insisted that he practice Phowa for him. Innocently he
complied with the request. At the end of the practice, he shocked
to see that the old man had passed away - the Phowa had worked only
too well! Immediately he started to practice again, to revive the
corpse lying there in front of him. To his immense relief, the old
man came back to life, but instead of thanking him, he shouted,
"For heaven's sake, why did you bring me back? I was already in the
Pure Land of the Buddha Amitabha!" Today, the old man's great
grandson works at Rinpoche's monastery in India.
