How does Chapter 28 of the Shri Sai Satcharitra describe Sai Baba's omnipresence and nature as a Sadguru?

Chapter 28 of the Shri Sai Satcharitra begins by establishing Sai Baba's omnipresent nature. The text states that Sai dwells in all beings, from the highest deity, Brahma, to the smallest ant and insect, pervading all of existence. He is not separate from anyone. Furthermore, this chapter describes him as a perfect Sadguru, being complete in Shabda-Brahma (the divine word) and showing the signs of Para-Brahman (the Supreme Being). This proficiency in both the manifest and unmanifest aspects of the divine is presented as a key quality of a true Guru.
