What was the business proposal that Damu Anna received from Mumbai, and what was his reaction?

Damu Anna received a letter from a friend in Mumbai proposing a business partnership. The plan, as detailed in chapter 25, was to buy cotton, with the friend predicting that the price would rise instantly. The friend projected a substantial net profit of two lakh rupees, which would be split evenly, giving each partner a one lakh rupee profit. The letter urged Damu Anna to act quickly and be 'smart,' describing the business as 'clean and safe' and warning that those who don't seize such opportunities often repent later. Upon receiving this proposal, the scripture states that Anna's mind was thrown into a turmoil, indicating he was conflicted and uncertain about how to proceed with this tempting offer.
