What is the main theme and overall significance of Chapter 45 in the Shri Sai Satcharitra?

Chapter 45 serves as a profound reflection on the power of the Guru and the void left by Sai Baba's physical departure. It emphasizes that serving the Guru’s feet is even more powerful than attaining Moksha, or liberation, as it makes worldly life happy and the impossible possible. The chapter highlights that although Sai Baba's physical form has vanished, His literary form, this very Satcharitra, remains to provide remembrance and guidance. As detailed in Chapter 45, listening to these stories with a concentrated mind is considered a supremely holy act that brings unique and indescribable peace to the devotee.
