What is the overall significance of Chapter 45 in the context of the Shri Sai Satcharitra?

Chapter 45 serves as a concluding reflection on Sai Baba's life, his departure, and his enduring legacy. The chapter poignantly expresses the loss of his physical presence while simultaneously providing the solution: his continued existence through his 'literary form,' the Satcharitra. As highlighted throughout this chapter, it reaffirms the supreme power of the Guru, who can make the impossible possible, and establishes the book itself as a holy medium for devotees to achieve peace, concentration, and remembrance of Sai Baba.
