Where does the book say Ratanji met Gajanan Maharaj?

The provided text does not state that Ratanji ever met Gajanan Maharaj. In fact, the name Gajanan Maharaj does not appear in these excerpts from Chapter 14. The narrative clearly states that after Ratanji made his resolution, he 'arrived in Shirdi.' Following his arrival, he went to the Masjid for darshan where he 'prostrated at Sai's feet.' Therefore, the Maharaj that Ratanji met was Sai Baba in Shirdi, who he hoped would help him with his desire for a son, as detailed in Chapter 14.
