How did Damu Anna react to Sai Baba's initial rejection of his business proposal, and what action did he take afterward?

Damu Anna was deeply disappointed and crestfallen upon receiving Sai Baba's reply. Chapter 25 describes how the "fortress of his desires crumbled" and the "tree of hope was uprooted." He felt he had caused his own harm by writing the letter. However, the letter also contained a hint from Madhavrao: "There is a difference between hearing and seeing; you should come here in person." Heeding this suggestion and still hoping for permission, Damu Anna traveled to Shirdi to meet Baba directly. Upon arriving, he sat near Baba and massaged his feet but found he lacked the courage to ask about the matter again.
