What is the primary theme conveyed in Chapter 45 of the Shri Sai Satcharitra?

The primary theme of Chapter 45 is the enduring and accessible grace of the Guru, Sai Baba, even after the end of His physical incarnation. The chapter begins by extolling the supreme power of the Guru, whose mercy makes the impossible possible. It then transitions to a poignant reflection on the loss of Sai's physical form, which had provided countless spiritual benefits. However, as Chapter 45 concludes, it offers profound reassurance by presenting the book itself, the Shri Sai Satcharitra, as Sai's 'literary form.' This literary form, along with listening to His stories, becomes the new medium for devotees to experience His presence, attain peace, and perform a holy act.
