The book mentions a 'Maharaj'. Is this a reference to Gajanan Maharaj?

Based on the provided text, the figure referred to as "Maharaj" is not Gajanan Maharaj. The narrative in Chapter 0 clarifies that this "Maharaj" is the person who came to be known as Sai Baba. The text explains that upon his arrival at the Khandoba temple in Shirdi, a devotee named Mhalasapati greeted him by saying "Aavo Sai Baba." As Chapter 0 states, Maharaj held that name "Sai Baba" until the end, and when his testimony was later taken in a commission, he gave his name as "Sai Baba."
