What does Chapter 28 say about the fundamental nature of Sai and His presence in the universe?

Chapter 28 begins by establishing the all-pervading nature of Sai Baba. It teaches that Sai is not separate from anyone and, in fact, dwells in all beings. This universal presence is described as extending from the highest celestial being, Brahma, down to the ant and the smallest insect, signifying that He pervades all, everywhere. The chapter further elaborates that Sai is complete in Shabda-Brahma (the divine word) and exhibits the signs of Para-Brahman (the Supreme Being). These are presented as the defining characteristics of a true Sadguru.
