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

Chapter 28 of the Shri Sai Satcharitra teaches that Sai is not separate from anyone and dwells in all beings, from the highest deity Brahma down to the smallest ant and insect. The text states that He pervades all, everywhere. It further defines the qualities of a Sadguru, explaining that Sai is complete in Shabda-Brahma (the divine word) and shows signs of the Para-Brahman (Supreme Being). The chapter emphasizes the Guru's immense compassion by contrasting it with a father's role; while a father gives birth to a body that will eventually die, the Guru has the power to remove the cycle of both birth and death for the devotee.
