What are the main points discussed in the introductory parts of Chapter 21 of the Sai Satcharitra?

Chapter 21 of the Sai Satcharitra begins by emphasizing the importance of the listener's emotional and physical response to the stories being told, stating that narrations are futile if they don't evoke delight and tears of love. The author then transitions to the idea that meeting Saints is not a matter of chance but requires good fortune. To illustrate this, he shares his personal story from when he was a Magistrate and failed to visit the Siddha Pir Maulana due to his own pride. Finally, as found in Chapter 21, the text introduces the concept that all Saints are inwardly one and inseparable, even if they appear in different times and places.
