Tell me about the financial advice Ratanji received from his business partners regarding his problem.

The provided source material from chapter 14 makes no mention of Ratanji's business partners or any financial advice they may have given him. The core of Ratanji's problem was deeply personal and spiritual, not financial; he was a very wealthy merchant who was unhappy because he had no son. The only counsel he is described as seeking and receiving is from Das Ganu. As chapter 14 narrates, this advice was purely spiritual: to go to Shirdi and surrender his troubles at the feet of Sai Baba. The focus is entirely on a spiritual remedy, not a worldly or financial one.
