How does the author of Chapter 21 use his past experience in Bandra to illustrate the principle of needing grace to meet a saint?

In Chapter 21, the author masterfully uses his own past as a cautionary tale to illustrate a deep spiritual truth. He confesses that as a Magistrate in Bandra, his pride and ego prevented him from visiting the Siddha, Pir Maulana. He frames this failure not just as a personal choice but as a consequence of "ill-luck" standing in his way. This personal anecdote serves as the primary evidence for the chapter's main argument: encountering saints is not a simple matter of proximity but requires divine grace. As the chapter states, this union is "easy only when God’s grace is present," connecting his personal story to the universal principle that one cannot see a saint if fortune is not on their side.
