How does Chapter 21 describe the nature of Saints and their interconnectedness across different times and places?

Chapter 21 offers a profound insight into the spiritual unity of Saints. It posits that although Saints may take incarnations in different places and at various times to fulfill specific purposes, they are "essentially inseparable from one another." The text emphasizes that despite differences in country or era, the signs of one Saint are completely known by another, because "Inwardly, they are all one." This section of Chapter 21 reveals the idea of an ancient, secret arrangement among Saints, suggesting a unified spiritual network operating behind the scenes, a concept that transcends individual manifestations.
