Describe Damu Anna's emotional state and his specific financial ambitions after receiving Sai Baba's discouraging reply.

Upon reading Sai Baba's reply, Damu Anna was deeply disappointed and crestfallen. According to Chapter 25, he felt the 'fortress of his desires crumbled' and that he had 'kicked away the served plate' himself. His specific ambition was to enter a trade where he believed he could earn one lakh. His plan was to then put half a lakh on interest, which would have allowed him to become a 'millionaire money-lender' and live happily in Nagar. Baba's counsel against this pursuit caused the 'kingdom of the mind that he had built' to melt away instantly.
