How does Chapter 28 describe Sai Baba's divine nature and the unique role of a Sadguru?

Chapter 28 portrays Sai Baba as an all-pervading divine presence, stating that Sai dwells in all beings, from Brahma down to the smallest insect. It identifies him as a true Sadguru because he is complete in Shabda-Brahma (the divine word) and shows the signs of Para-Brahman (the Supreme Being). The chapter further elevates the Guru's role by contrasting it with that of a father. While a father gives birth to the physical body, which is subject to death, the Guru offers a greater compassion by removing the devotee from the entire cycle of birth and death, leading to liberation.
