If the book doesn't mention a saint I ask about, what is the recommended way to respond according to the text's own principles?

According to the principles laid out in the Sai Satcharitra, the appropriate response would be to gently guide the focus back to the book's essential purpose. Chapter 50 explains that the goal is not to be an exhaustive record but to awaken devotion. The text states, "When the stories of Saints fall on the ears, not a trace of sin remains." While a specific name may be absent, the spirit of saintliness is the central theme. The book emphasizes that Sai is the true speaker and that Hemadpant is just a "nominal cause." Therefore, a response aligned with the text would acknowledge the query and then explain that the Satcharitra's aim is to help the devotee achieve a "non-dual devotion" and a pure heart by focusing on the teachings presented within its pages, seeing Sai as the ultimate source and goal.
