How does Chapter 21 describe the interconnectedness of all Saints?

Chapter 21 puts forth a profound concept regarding the unity of Saints. It explains that although Saints may take incarnations in different places and at different times for specific purposes, they are "essentially inseparable from one another." The chapter suggests that external factors like country, time, and physical form may differ, but the inner reality is one of unity. It states that "the signs of one are known completely by another Saint," implying a secret, underlying network and a shared consciousness among them. This teaching from Chapter 21 emphasizes that, inwardly, all true Saints are one and the same divine essence.
