Chapter 21 discusses the nature of Saints and their interconnectedness. Can you explain this concept based on the text?

Chapter 21 of the Sai Satcharitra presents a profound concept about the unity of Saints. The text explains that Saints may take incarnations in different places and at different times for specific purposes, making them appear distinct. However, the author emphasizes that they are "essentially inseparable from one another." As stated in Chapter 21, although the country, time, and circumstances may differ, the inner signs of one Saint are completely known to another. This suggests a universal, underlying consciousness or spiritual essence that unites all true Saints, making them inwardly one, regardless of their external form or location.
