How does Chapter 28 describe Sai Baba's omnipresence and his nature as a Sadguru?

Chapter 28 beautifully illustrates Sai Baba's all-pervading nature, stating that Sai dwells in all beings, from the highest deity, Brahma, to the smallest ant and insect. The chapter explains that He is complete in Shabda-Brahma (the divine word) and shows the signs of Para-Brahman (the Supreme Being). This proficiency in both aspects is what gives Him the quality of a Sadguru. Furthermore, the text highlights the Guru's profound compassion, noting that while a father gives birth to a body subject to death, a Guru like Sai has the power to remove the cycle of both birth and death.
