The application was created to stimulate the reading of the Book of Spirits at any time of the day. A stimulus for reading when you are not with a book nearby, whether you are on the bus, at a free time in the study / work. The choice of text is random, each will only repeat when all parts of the book are chosen. When you open a section, below you will have a button available to view the whole chapter if you want to better understand the context of what you have read.
