Much understand, much problem. Little understand, little problem. Complete DON'T KNOW, no problem.
Buddha said very clearly that humans have five main desires: food, sleep, sex, money, fame. As we grow these five desires all become stronger. So the real Mind Revolution comes from looking back at ourselves. Looking into “I.” Don’t worry about finding anything. Just by looking into “I,” things change. You don’t have to believe in Buddhism. It is not Buddhism; it is just a human being having a big question. That’s all.
The five desires are important to satisfy, but if that is all your life is, you will never be happy. Look back at yourself. What am I? Don’t know. That is the true treasure—so valuable. Then you can change your relationship with the five desires and even use them to help all beings. That is the real Mind Revolution.
