The book includes three stories and stories about a variety of people - about businessmen and alcoholics, about doctors and homeless people, about priests and suicides. The main characters are trying to find answers to eternal questions: what should we devote ourselves to in this life? What is better: to serve yourself or to be served? Can earthly love grow into heavenly love? How to distinguish friends from enemies in everyday life? how to clear your vision in order to clearly distinguish light from darkness? These stories and tales teach a person not to give up in the most hopeless life situations; keep your word; being at a crossroads, always prefer good to evil, no matter what temporary sacrifices this may involve. Because, as the classic said, the human heart is a battlefield where the devil fights with God. Every person is at the epicenter of hostilities, and only those who renounce themselves in order to find their true selves will survive.
