Bokononism is based on the concept of foma, which are defined as harmless untruths. A foundation of Bokononism is that the religion, including its texts, is formed entirely of lies; however, one who believes and adheres to these lies will have peace of mind, and perhaps live a good life. The religion's bible, The Books of Bokonon, begins: "Don't be a fool! Close this book at once! It is nothing but foma! All of the true things that I am about to tell you are shameless lies." The primary tenet of Bokononism is to "Live by the foma that make you brave and kind and healthy and happy."
