If anybody asks if Buddhists believe in reincarnation, you should say, “As Buddhists we don’t believe in any dogma. We believe what we experience.” That’s the key word: experience. In fact, studying karma or any aspect of the buddhadharma, the Buddhist teachings, has nothing to do with promise, absolutely nothing to do with it at all. The point of our study is to see that promises and looking for promises does not make any sense. We have to get ourselves together, pull up our socks, go to work, earn money, and get our psychological state together. It’s very simple.
