How does Chapter 21 explain the relationship and connection between different Saints?

Chapter 21 presents the teaching that all Saints are part of a unified, secret arrangement and are 'inwardly one.' The text explains that although Saints may take incarnations in different places and at different times for specific purposes, they are 'essentially inseparable from one another.' This implies a deep spiritual connection where the country, time, and external objects may differ, but the essence remains the same. The chapter further notes that the signs of one Saint are completely known by another, highlighting their profound interconnectedness within a divine network.
