Can you tell me about the story of the author's friend in Lonavala and how it might relate to the author's journey?

Chapter 2 recounts a tragic event that occurred on the very day the author was supposed to depart for Shirdi. A close friend, who was the son of a Guru, was in Lonavala with his family. His only healthy and virtuous son was suddenly stricken with a fever. Despite trying all human remedies and even having the Guru himself sit by the boy's side, the son ultimately passed away. This difficult situation, where even the physical presence of a Guru could not prevent the death, is presented as a stark example of a crisis where all efforts were in vain. While the text doesn't explicitly state the author's reaction, this story is placed right after describing his cynical and logic-driven mind, suggesting it may have been a pivotal event that challenged his intellectual pride and made him question the limits of human and even spiritual intervention.
