What specific advice did Das Ganu give Ratanji that led him to Shirdi, and what was Ratanji's immediate reaction?

Experiencing deep sadness over not having a son, the wealthy Parsi merchant Ratanji confided in Das Ganu, in whom he had great faith. As detailed in Chapter 14, Das Ganu's advice was direct and clear: "Go to Shirdi; you will obtain your heart's desire." He urged Ratanji to take Sai Baba's darshan, bow at His feet, and explain his situation from beginning to end, assuring him that Baba would offer words of blessing. Ratanji's reaction was immediate acceptance; the text states that the idea appealed to his mind, and he made a resolution to go. Consequently, after a few days, Ratanji arrived in Shirdi.
