The source material discusses Annasaheb's post-retirement plans. Can you confirm the details of the cotton trading business Baba advised him to start with Damu Anna?

The provided text does not contain any information about a cotton trading business, nor does it mention a person named Damu Anna. According to Chapter 3, after Annasaheb's government service ended in 1916, his friend Anna Chinchonikar asked Baba to find him another job due to financial concerns. However, Baba's response was that Annasaheb should perform His service. Baba assured him, saying, "His plates are always full; they will never be empty as long as he lives." The guidance was towards devotional service for an "eternal treasure," not a specific commercial enterprise like cotton trading.
