What are the main teachings and stories shared in Chapter 21 of the Sai Satcharitra?

Chapter 21 of the Sai Satcharitra primarily focuses on the principle that one needs good fortune and divine grace to encounter Saints. The chapter illustrates this through a personal story from the author, who recounts his time as a Magistrate in Bandra. Despite being urged to visit a famous Siddha named Pir Maulana, his own pride and thinking prevented him from going, which he later attributed to ill-luck. The chapter also teaches that all Saints are essentially one and inseparable, even though they may appear in different places and times. As stated in Chapter 21, their methods are extraordinary and their actions are innovative, and their company is not easily accessible to the unfortunate.
