After the initial rejection via letter, what prompted Damu Anna to visit Shirdi, and what happened when he arrived?

Although initially disheartened, Damu Anna decided to visit Shirdi in person because of a hint included in the reply letter from Madhavrao (Shama). Chapter 25 states that the letter suggested, 'There is a difference between hearing and seeing; you should come here in person.' Holding onto the hope that he might still receive permission for his venture, Damu Anna traveled to Shirdi. Upon arriving, he sat near Baba and began to massage his feet, but ultimately, he found that he had lost the courage to ask about the business plan again.
