What are the key spiritual themes introduced at the beginning of Chapter 9 of the Sai Satcharitra?

The beginning of Chapter 9 introduces several profound spiritual themes that are explored in the subsequent stories. First, it highlights the negative consequences that befall devotees who return home from Shirdi without Sai Baba's permission. Second, it explains that Baba's lifelong habit of begging for food was not for himself, but for the welfare of his devotees and for the removal of sins. Finally, Chapter 9 posits a core Vedantic truth: that Sai is pervaded everywhere, from the creator Brahma to the smallest inanimate object, and that God resides in all beings. These themes set the stage for the stories that follow, which illustrate Baba's mercy and omniscience.
