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

Chapter 21 of the Sai Satcharitra presents a profound teaching on the nature of saints. It states that saints may take incarnations in different places and at different times for specific purposes, but they are essentially inseparable from one another. The text clarifies that while the country, time, and objects associated with them may differ, the signs of one saint are completely known to another. This is because, as Chapter 21 reveals, inwardly and spiritually, all saints are fundamentally one.
