This book is a guide on how a deceased person should behave in the World Beyond. You read it at the grave of the dead person. At the same time, you can view the book as advice for the living—what you should be ready for, during life, with respect (unfortunately) to the inevitable passing from here.
This book is about what happens when a person dies, and how to prepare for what awaits at the Border and after it—until, as the book claims, the person falls back again into unconscious Existence.
