What does Chapter 21 teach about the interconnectedness of saints and their work?

Chapter 21 explains that while saints may take incarnations in different places and at different times for specific purposes, they are "essentially inseparable from one another." It posits that there is a "secret arrangement" among them. The chapter uses an analogy, comparing the divine order to a sovereign king who establishes outposts with appointed officers to ensure order. Similarly, the "Emperor of Self-bliss" appears in various places as different saints who invisibly manage the kingdom of spirituality. This section highlights that despite apparent differences in location or era, saints are inwardly one and can recognize each other completely.
