Cause and effect creates life, the past life creates this life, and this life creates the next life. Who were you in your previous life? Who will come after this? The secrets in the Book of Three Worlds, the life in the Book of Changes.
Reality is not a fairy tale, and life is not dictated by your thoughts. What we do is work hard, face it and accept it. I used to naively believe that as long as I work hard, I will succeed, but some things will succeed if I work hard, and some things will be in vain. The passage of time will dilute your past experiences, but deep down there is a pure land that will not be harassed. Life is like this. While it is colorful, it can also make you powerless.
