I'm trying to understand the book's core philosophy. If I ask about a different spiritual master, what does the Satcharitra itself say about how to handle that?

The Sai Satcharitra's core philosophy, particularly as articulated in Chapter 50, would redirect that inquiry back to the nature of devotion and the book's singular purpose. It doesn't engage in comparative theology but instead focuses on a specific spiritual path. The text states a preference for "steady devotion to Sai" over the four types of liberation, framing it as the ultimate goal. The author, Hemadpant, posits that he is merely a channel and that Sai is the true source of the words, the subject of the story, and the consciousness of the listener. Therefore, if asked about another master, the book's own logic would suggest that the reader should perceive Sai in their heart and maintain an unbroken non-duality, using the inquiry itself as an opportunity to deepen their one-pointed focus on the path prescribed within the Satcharitra.
