What advice did Sai Baba give to Damu Anna about investing in the cotton trade after his government service ended in 1916?

The provided source material does not mention Damu Anna or any cotton trade. The events described in Chapter 3 concern the author of the text, not Damu Anna. In 1916, after the author's government service was completed, it was a different person named Anna (Chinchonikar) who spoke to Sai Baba on the author's behalf. Anna Chinchonikar expressed concern that the author's pension would be insufficient and asked Baba to find him another job. Baba replied that the author should perform His service, assuring him that his "plates are always full; they will never be empty as long as he lives." The conversation was about service and faith, not commercial investments like the cotton trade.
