What are the central teachings presented in Chapter 28 regarding Sai Baba's omnipresence and His methods of guiding devotees?

Chapter 28 presents several core teachings about Sai Baba's divine nature and methods. It begins by establishing His omnipresence, stating that Sai dwells in all beings, "from Brahma to the ant and the smallest insect." It defines Him as a Sadguru who can liberate devotees from the cycle of birth and death. The chapter then focuses on a key method of His guidance: appearing in devotees' dreams. Through these dreams, He removes troubles, corrects behavior, and creates deep love for Him. This is exemplified by His famous promise to pull devotees to Him like a sparrow on a string, a concept illustrated through the introduction of the devotee Laxmichand.
