Through the Maze of Chartres on the Path to Yourself [EPUB ebook] 

The book describes how to use the maze on the floor of Chartres Cathedral as a template for further development in one’s spiritual life. Every labyrinth is a challenge — just like our lives. The Chartres labyrinth is a real gold mine of resources on the way to ourselves. Not only the walk inside, but every petal in the middle of it stands for a teaching that can already be found in the Our Father. If you walk through the labyrinth with all six petals and reach the middle, which stands for the essence and the source of love, you have completed a perfect spiritual exercise.
