Can you describe the narrator's personal experience in Bandra as detailed in Chapter 21? Who was the Siddha, and why didn't the narrator visit him?

In Chapter 21, the narrator recounts that while he was the Magistrate in the city of Bandra, a famous Siddha named Pir Maulana resided there. The Siddha's servant, Inus, followed the narrator day and night, urging him to come for a vision. However, the narrator confesses that thoughts like "Why should I go? Should I be pressured by others and lose my own prestige?" filled his mind. He attributes this reluctance to his own ill-luck, stating that "One fears one's own shadow when ill-luck stands in the way." As a result of this mindset, he never went for the vision during his many years there.
