What are the primary themes and teachings presented in Chapter 9 of the Sai Satcharitra?

Chapter 9 of the Sai Satcharitra focuses on several key teachings. It emphasizes the significant troubles and exhaustion faced by devotees who left Shirdi without Sai Baba's permission. The chapter also explains the spiritual purpose behind Baba's habit of begging for food, which he did for the welfare of his devotees and to absolve them of sins like the 'Panchasuna'. Furthermore, as Chapter 9 conveys, a central theme is the omnipresence of God, with Sai being pervaded everywhere and residing in all beings, from Brahma to the smallest inanimate object. Devotees are urged to listen attentively to these holy stories to achieve their own welfare.
