What are the primary teachings and stories presented in the available excerpts of Chapter 21 of the Sai Satcharitra?

Based on the provided sections of Chapter 21, the main teaching is that one cannot encounter Saints and Sages unless good fortune dawns and God’s grace is present. The text emphasizes that this holy company is not accessible to the unfortunate. To illustrate this, the author shares a personal story from his time as a Magistrate in Bandra. He recounts how he repeatedly refused to visit a famous Siddha named Pir Maulana, attributing this failure to his own "ill-luck" standing in the way. Chapter 21 also philosophically states that while Saints may appear in different times and places, they are essentially inseparable and inwardly one, knowing each other completely.
