I'm looking for the part where Gajanan Maharaj advises Ratanji about his lack of a son. Which chapter is that in?

Based on the provided source material from Chapter 14, it was Das Ganu who advised the Parsi merchant Ratanji to visit Shirdi. Ratanji then went to the Masjid and met with Sai Maharaj, also called Baba, to seek a blessing for a son. The text describes Ratanji's offering and his prayer to Sai Baba. The name Gajanan Maharaj does not appear in these excerpts, and he is not mentioned as being involved in Ratanji's story.
