What does Chapter 28 say about the nature of a Sadguru and their compassion?

Chapter 28 of the Shri Sai Satcharitra explains that a Sadguru, like Sai Baba, is proficient in both Shabda-Brahma (the divine word) and shows signs of Para-Brahman (the Supreme Being). The text suggests that the quality of a Sadguru can belong to a great knower who imparts teachings or one who is simply established in their own true nature. A powerful comparison is made to highlight the Guru's unique compassion: while a father gives birth to the body, which is subject to death, the Guru removes the cycle of both birth and death, an act described as an 'additional compassion' beyond that of a parent.
