How does the author in Chapter 21 use his own experience to illustrate a spiritual principle?

In Chapter 21, the author, Hemadpant, uses his own past to illustrate the principle that meeting a Saint is a matter of destiny and grace, not personal effort or proximity. He recounts his time as a Magistrate in Bandra when he consciously chose not to visit the revered Siddha, Pir Maulana, despite being repeatedly invited. He reflects on this decision, as shared in Chapter 21, not as a simple choice but as a consequence of his 'ill-luck' and pride. By sharing this personal failure, he proves his point that 'unless good fortune dawns, one does not encounter Saints and Sages; even if He is near one's pillow, the sinful person cannot see Him.' His subsequent unbreakable bond with Shirdi further emphasizes that the right time and divine will are paramount.
