Who are guardian angels and how do they protect us? Why do they protect against troubles, misfortunes, premature death, help get rid of fear, melancholy or pain? And why do we trust these mysterious creatures, which cannot be seen with ordinary vision, sometimes more than ourselves? This book tells about the guardian angels who accompany a person on his life path from birth to death, and about the patron saints who appear to every Christian in moment of making a sacred decision. The reader will learn how to establish contact with his guardian angel and what prayer to turn to him in difficult times.
