How can I apply the teachings of this book if my devotion is directed towards a different spiritual figure, like Krishna, and not Sai Baba?

Chapter 19 provides a profound key to this very question. It highlights the principle, "'Ye yatha mam' (As they approach me...),'" which places the responsibility squarely on the devotee's own actions and approach. It further states, "As the action, so the hearing; as the practice, so the benefit." The text gives a direct example where the author, deciding to focus on Rama, then hears a song about Rama. This illustrates that if you approach with an undivided heart full of devotion, whether for Krishna or another, the teachings on surrender and faith will yield their fruit.
