God has given us the ability to experience a wide variety of emotions. Of course, this does not mean that we should give them free rein; on the contrary, we should be able to control them, manage them. There is also no need to rush from one extreme to another: either not show emotions at all, or give vent to every emotion without considering whether it is appropriate. In this book, the author talks about how our emotions can serve us and how to keep them under control.
