How does the story of Ratanji connect to the Zoroastrian concept of 'Asha' or divine truth?

The provided excerpts from chapter 14 do not make any connection between Ratanji's story and the Zoroastrian concept of 'Asha' or any other specific Zoroastrian tenet. Although Ratanji is identified as a "famous Parsi merchant; very religious and popular," the narrative does not delve into his specific religious philosophy. Instead, the story focuses on his universal human problem—the desire for a son. As chapter 14 explains, his solution comes not from his own faith's doctrines but from the advice of Das Ganu to seek out Sai Baba in Shirdi, a figure who welcomed Hindus, Muslims, and Parsis alike.
