Can you tell me about the educated officer who became a Collector mentioned in Chapter 21?

Certainly. Chapter 21 introduces the story of a man who was highly educated in English and held a B.A. degree. He progressed steadily in his career, first obtaining the post of Mamlatdar and eventually rising to become a Collector. The chapter highlights that it was due to his "good fortune" that he obtained the company of Sai Baba. The text also provides a brief commentary on his role as a Mamlatdar, comparing the post to a hill that looks beautiful from afar but is surrounded by thorny bushes up close, suggesting the job was more difficult than it appeared. This story is used to show how people from all walks of life, including high-ranking officials, were drawn to Sai.
