How does Chapter 28 describe the all-encompassing nature of Sai Baba and his qualities as a Sadguru?

Chapter 28 of the Shri Sai Satcharitra teaches that Sai Baba is not separate from anyone and dwells in all beings, from Brahma down to the smallest ant and insect. The text emphasizes that He pervades all, everywhere. This chapter further explains his qualities as a Sadguru, noting that he is complete in Shabda-Brahma (the divine word) and shows signs of Para-Brahman (the Supreme Being). Being proficient in both of these aspects is presented as a defining quality of a Sadguru. The text also contrasts a Guru with a father, stating that while a father gives birth to a body that will eventually die, a Guru's compassion is greater as he removes the entire cycle of birth and death.
