How does Chapter 21 describe the relationship between different saints, even if they appear in different times and places?

Chapter 21 puts forth the teaching that all true saints are fundamentally united and inseparable, despite appearing in different locations or eras. The text explains that 'inwardly, they are all one.' To illustrate this concept, it uses the analogy of a sovereign king who establishes outposts in various regions, with officers appointed to maintain order. In the same way, Sai Baba, described as the 'Emperor of Self-bliss,' and other saints act as spiritual officers in different places, invisibly managing a single, unified spiritual kingdom for the benefit of humanity.
