According to Chapter 21, what is the connection between all Saints, and how does it relate to their incarnations?

Chapter 21 of the Sai Satcharitra explains a profound and mystical connection between all Saints. It teaches 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 states that while their external circumstances like country, time, and appearance may differ, they are all inwardly one. This unity allows one Saint to completely know the signs and nature of another. The text emphasizes that this is part of the "secret arrangements" of Saints, highlighting their transcendental and unified consciousness that goes beyond physical and temporal boundaries.
