Can you explain the main themes introduced at the beginning of Chapter 9?

The beginning of Chapter 9 introduces several key themes that are central to the narrative. It highlights the trouble and exhaustion suffered by devotees who returned to their homes without first securing Sai Baba's permission. The chapter also explains that Baba's lifelong habit of begging for food was for the welfare of his devotees and the removal of their sins. Furthermore, a profound spiritual teaching is presented: the idea that Sai is pervaded everywhere, from the highest deity, Brahma, to the smallest inanimate object, impressing upon us that God resides in all beings.
