If the Satcharitra only talks about Sai Baba, doesn't that make its perspective on sainthood very narrow? How does it justify this singular focus?

The Shri Sai Satcharitra justifies its focus on Sai Baba by presenting him as the embodiment of a universal principle. Chapter 50 clarifies that Hemadpant is merely a "nominal cause" and that "there is no one other than Sai who makes the words speak." The text instructs the reader to see the subject, the act of reading, and the reader as a single, unified state. By focusing intensely on Sai, the goal is to achieve a state where "all the tendencies of the senses certainly become Sai-form." This suggests the focus isn't narrow, but rather a profound method for realizing non-duality. The book posits that through devotion to the Saint, the heart becomes pure, which is a universal spiritual attainment, not a limited one.
