Who was it that advised the merchant Ratanji to go to Shirdi for help?

Ratanji, who was always sad about not having a son, had great faith in a person named Das Ganu. As recounted in Chapter 14, Ratanji confided in Das Ganu, revealing the secret sorrow of his heart. In response, Das Ganu advised him to go to Shirdi and seek the darshan of Sai Baba. Das Ganu assured Ratanji that if he bowed at Baba's feet and explained his problem, Baba would give him words of blessing and fulfill his heart's desire, emphasizing that Baba's power was inconceivable and that surrendering to Him would bring fulfillment.
