How does the author's personal story about Pir Maulana connect to the chapter's main teaching about needing 'God's grace' to meet a saint?

The author uses his own past experience to powerfully illustrate a key teaching in Chapter 21: that the company of saints is not easily attained and requires divine grace. He recounts how, as a Magistrate in Bandra, his pride and what he calls "ill-luck" prevented him from visiting the Siddha Pir Maulana, even though the saint was nearby. He directly links this failure to the principle that "this company of Saints is not accessible to the unfortunate; It is easy only when God’s grace is present." His inability to see the saint in Bandra contrasts with his later deep connection to Shirdi, which he describes as an "unbreakable bond," implying that his time for such grace had finally come.
