What were Damu Anna's specific aspirations that Sai Baba advised against, and what was his immediate feeling of loss?

Damu Anna aspired to become a millionaire through a speculative business venture. Chapter 25 reveals his mindset after receiving Baba's discouraging reply. He lamented the opportunity, thinking to himself, "I would have earned one lakh now, and put half a lakh on interest. I would have immediately become a millionaire money-lender and lived happily in Nagar." His immediate feeling was one of immense disappointment and regret. The text states that the "kingdom of the mind that he had built melted away on the spot," leaving him very crestfallen and feeling as though he had personally "kicked away the served plate" that fortune had offered.
