How does the author contrast his experience in Bandra with his later connection to Shirdi in Chapter 21?

In Chapter 21, the author draws a stark contrast between his past and present spiritual fortunes. He narrates his experience in Bandra where, as a Magistrate, he was unable to visit the revered Siddha, Pir Maulana, due to his own pride and what he terms "ill-luck." Many years passed, and he was transferred without ever having the Saint's vision. He then juxtaposes this failure with his subsequent experience, stating, "Later, when that time came, Shirdi became an unbreakable bond." This contrast serves a powerful purpose in the narrative of Chapter 21, illustrating the central theme that the company of Saints is only possible through God's grace and when the destined time arrives.
