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

Chapter 9 of the Shri Sai Satcharitra focuses on several key teachings. A central theme is the absolute importance of receiving Sai Baba's permission before leaving Shirdi, as departing without it invites obstacles and trouble. The chapter illustrates this with accounts of devotees who suffered for not heeding this rule. It also explains that Baba's lifelong habit of begging for food was a spiritual practice for the welfare of his devotees, meant to remove their sins. Furthermore, Chapter 9 imparts the profound philosophical concept that Sai is omnipresent, pervading all of creation from Brahma to the smallest inanimate object, thereby teaching that God resides in all beings.
