How did Damu Anna react to Sai Baba's advice against his business venture, and what does it reveal about his mindset?

Damu Anna's initial reaction to Sai Baba's advice was one of extreme disappointment and regret. According to Chapter 25, upon reading Baba's reply advising against the venture, the "fortress of his desires crumbled" and he became very crestfallen. He lamented that he had "kicked away the served plate" himself, imagining the millions he could have earned. This reveals that his mindset was heavily focused on material gain and worldly ambition, as the chapter states the "kingdom of the mind that he had built melted away on the spot." His profound disappointment shows how attached he was to the idea of becoming a millionaire.
