How does Chapter 28 describe the nature of Sai Baba and the qualities of a Sadguru?

Chapter 28 explains that Sai is not separate from anyone, but dwells in all beings, pervading everything from the highest being, Brahma, to the smallest insect. The text states He is complete in Shabda-Brahma (the divine word) and shows signs of Para-Brahman (the Supreme Being), which are qualities of a Sadguru. Furthermore, the chapter contrasts a father, who gives birth to the physical body which is subject to death, with a Guru, who offers the greater compassion of removing the entire cycle of birth and death. These descriptions, found in the opening verses of Chapter 28, highlight Sai's omnipresence and the profound spiritual role of a true Guru.
