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

Chapter 28 of the Shri Sai Satcharitra explains that Sai Baba is omnipresent, dwelling in all beings from the highest celestial being to the smallest insect. The text describes Him as being complete in Shabda-Brahma (the divine word) and showing signs of Para-Brahman (the Supreme Being), which are definitive qualities of a true Sadguru. This chapter further elevates the Guru's role above that of a father; while a father gives birth to a body subject to death, a Guru offers profound compassion by providing a path to overcome the entire cycle of birth and death.
