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

Chapter 9 of the Shri Sai Satcharitra focuses on several key principles for devotees. It strongly emphasizes that pilgrims should never depart from Shirdi without first obtaining Sai Baba's permission, as doing so invites obstacles and trouble. The chapter also explains that Baba's lifelong practice of begging for food was not for his own sustenance but for the spiritual welfare of his devotees, specifically for the removal of sins. Furthermore, Chapter 9 imparts the profound teaching that Sai is omnipresent, pervading everything from Brahma to the smallest inanimate object, thereby impressing upon followers that God resides in all beings. These holy stories are presented as a means for devotees to achieve their own welfare.
