It’s so difficult to discern between a ghost and a Buddha or a Saint, because the Saint, normally, They don’t even use any power, don’t predict much. Even just to want to know past lives, you’ll be in trouble too. There was one Master in Korea a long time ago, He didn’t teach much to his disciples. He said, "Whatever happens or turbulence goes into your mind, you just say, ’Don’t know.’ " He wanted to break all of the trains of thought of his disciples，which was also maybe helpful. But don’t just “don’t know” anything, all right? You know you should be good, keep the precepts, meditate, eat vegan.
