Could you summarize the main teachings presented in Chapter 21 of the Sai Satcharitra, including the author's personal anecdote?

Chapter 21 of the Shri Sai Satcharitra teaches that encountering Saints is not a simple matter but requires good fortune and divine grace. The author powerfully illustrates this by sharing a personal story from his time as a Magistrate in Bandra. As narrated in the chapter, he was repeatedly urged to visit a renowned Siddha, Pir Maulana, but his pride and what he calls ill-luck prevented him from doing so. This experience demonstrates that even if a Saint is physically near, a meeting is not possible without destiny's sanction. Furthermore, the chapter explains that all Saints, despite appearing in different times and places, are inwardly one and inseparable, working together through a secret divine arrangement.
