Please compare the advice given by Sai Maharaj and Gajanan Maharaj to the Parsi merchant Ratanji.

According to the information in Chapter 14, the Parsi merchant Ratanji sought guidance from Sai Maharaj in Shirdi for his desire to have a son. The text details his arrival, his offerings, and the beginning of his interaction with Sai Baba, who immediately asks him for Dakshina. However, the provided source chunks make no mention of Gajanan Maharaj, so it is not possible to compare their advice as there is no record of Gajanan Maharaj interacting with or advising Ratanji in this account.
