What does Chapter 28 say about the nature of a Sadguru and how Sai Baba embodies these qualities?

Chapter 28 of the Shri Sai Satcharitra defines the qualities of a Sadguru and explains how Sai Baba embodies them. A Sadguru is described as one who is proficient in both Shabda-Brahma (the divine word) and shows signs of Para-Brahman (the Supreme Being). Furthermore, a true Sadguru is able to impart teachings to disciples. The text states that Sai Baba has these qualities. It also emphasizes that a Guru's compassion is greater than a father's; as this chapter explains, a father gives birth to a body subject to death, while the Guru removes the entire cycle of both birth and death, showing additional compassion.
