Excerpts from Supreme Master Ching Hai's lecture:
To look into the past record is a very terrible journey. It's no good. Like today, I had to look into someone's record, and sometimes that someone involves many others. It's not easy to look into someone's record and then see no one else involved around him. And it brings you into many other connections, and each one offers you whole a lot of... troublesome past lives, and sometimes it's not very good for you, when you're looking, not when you wake up. When you wake up, then of course because of our power of practicing the Quan Yin Method, we probably can immediately erase the depressed feeling or any kind of negative feeling that results from the past life effects. Sometimes the past life is very gruesome, awful and full of depression and suffering. Because we're connected with each other in this past history, and whatever happens to one affects the others as well. Past decades, past generations, past eras of our earth's history are mostly very dark. And if we're earth inhabitants we have gone through all these kinds of events, which are very difficult for us to forget. And should we be able to remember, it will give us such tremendous suffering and depression that we don't want to even know about it. That's why it's a blessing from the highest intelligence that we don't remember our past lives.
