Can you provide a summary of the main themes discussed in Chapter 45?

Chapter 45 begins with salutations and powerfully emphasizes the significance of the Guru's feet, stating they are even more powerful than Moksha (liberation). It then transitions into a poignant lament for Sai Baba's physical departure, noting that the form which granted bliss and removed worldly fear is now lost to sight. However, as Chapter 45 explains, it offers solace by presenting the Shri Sai Satcharitra as His new literary form, which will provide remembrance at every step. The chapter concludes by highlighting that listening to these stories is a supremely holy act that brings unique and indescribable peace.
