I'm looking for the story of Ratanji's meeting with Gajanan Maharaj. Can you summarize it?

There appears to be a misunderstanding, as the provided text details Ratanji's meeting with Sai Baba of Shirdi, not Gajanan Maharaj. According to Chapter 14, Ratanji was a prosperous Parsi merchant tormented by the fact he had twelve daughters but no son. This sorrow made his worldly happiness feel fruitless. A trusted acquaintance, Das Ganu, advised him to go to Shirdi and surrender to Sai Baba. Ratanji followed this counsel, traveled to the Masjid in Shirdi, and prostrated before Sai Maharaj, offering a flower garland and fruits while humbly presenting his plea for a child.
