Even though he was so disappointed, why did Damu Anna decide to travel to Shirdi after receiving the letter?

Damu Anna's decision to visit Shirdi in person, despite his initial disappointment, was prompted by a specific suggestion in the reply. According to Chapter 25, the letter contained a hint: "There is a difference between hearing and seeing; you should come here in person." Attributing this to a suggestion from Madhavrao, Damu Anna felt it was the right course of action. He harbored a renewed sense of hope, thinking to himself, "Who knows, there might be benefit in that too. Perhaps He will give permission." This hope of potentially changing Baba's mind in a face-to-face meeting motivated his journey to Shirdi.
