People who say that learning the Book of Changes will bring disaster actually want to warn ordinary people not to learn indiscriminately. Not everyone can understand the Book of Changes. It is profound, and disorderly learning will only lead them astray, which will naturally bring disaster.
As for "secrets can't be revealed", there are two kinds of people who say this. One is a liar and the other is a fool. They say this mainly to trick you into giving him more money, and also to keep their mystery so as to fool you. Another kind of person is a person who has real talent and knowledge and really understands the Book of Changes. They say this in two ways. First of all, they think it is better for you to know something than not to know it. Telling you may hurt you, so they won't say it, so they use this secret to gag themselves. Don't let you ask. Another situation is that they can't see through your affairs and can't help you. Some people will tell you that they have limited knowledge and can't help you. However, some people love face, so this sentence is to find their own steps.
Life-saving does not exist. Is to warn people not to learn nonsense. Otherwise, it will bring trouble to yourself or others. It's really time to save this person's life.
If you want to learn, you can. Many truths in the Book of Changes can teach us a better life. However, we should not blindly believe it. The word' Yi' means change, that is, flexibility. You can't read this book dead, you should learn to use it.
If you learn the Book of Changes to tell fortune, don't learn it. Unless you are a rare genius, if you are, you will naturally understand how this fate is "calculated" when you see the Book of Changes to a certain depth, and then you will know what to do. If not, don't use it to harm people. Be careful, it's really precocious.
