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

Chapter 45 emphasizes the supreme importance of the Guru, stating that serving the Guru's feet is even more powerful than achieving Moksha (liberation). It reflects on the loss of Sai Baba's physical form, which brought contentment and courage. However, as Chapter 45 explains, even though His physical form has vanished, His literary form, the Shri Sai Satcharitra itself, remains to provide remembrance, bring peace, and offer concentration to those who listen to the stories with a focused mind.
