Great spiritual teachers know not to take on other people’s karma. They don’t command or demand. If I tell you to tithe 10% of your income to the church, but then you don’t use your head, and do it even as your children starve, then I am partly responsible for their ill health. If I rail against abortion doctors and then you go out and blow up a hospital, that is partly my fault. A great teacher won’t tell you that you absolutely MUST do this, that you MUST believe that. A great teacher simply points, offers his own life as an example, and shows you love. You can follow, or not, even find your own way, and he will love you.
A great teacher is first and foremost a kind person and a caring soul.
Do I believe in miracles? No, not really. Do I believe that there have been, and are, great teachers and developed human beings who have raised others from the dead, multiplied food stores, pulled objects out of nothingness, and travelled long distances out of body? Absolutely. But I don’t see these things as miracles. There are many laws of Nature that science has not yet discovered, categorized, and mapped out in mathematical formulae. But they are still laws of Nature. Some metaphysicians have been able to work with them just as you and I work with gravity when we stand up or sit down. Just because they are outside what science recognizes doesn’t make them unnatural. And, since they are natural, and since those who make use of them are staying within natural laws, then I don’t see such things as being miracles.
