What does Chapter 21 say about the nature of Saints and their relationship with each other?

Chapter 21 delves into the profound nature of Saints, explaining that they are essentially one, despite appearing in different times, places, and forms. The text states that Saints take incarnations for specific purposes in locations they choose, but they are 'inseparable from one another.' This chapter emphasizes that while the country, time, and external circumstances may differ, the inner signs of one Saint are completely known by another. They share a unified, inner reality, and the text highlights how their 'secret arrangements work.' As Chapter 21 puts it, 'Inwardly, they are all one.' This reveals the universal and interconnected essence of all true spiritual masters.
