According to Chapter 28, what are the defining characteristics of a Sadguru like Sai Baba, and how does a Guru's role compare to a father's?

Chapter 28 of the Shri Sai Satcharitra provides a profound description of a Sadguru's qualities. It states that a true Sadguru like Sai is proficient in both Shabda-Brahma (the divine word) and Para-Brahman (the Supreme Being), and is able to impart this teaching to disciples. The chapter further elevates the Guru's role by comparing it to a father's. While a father gives birth to the physical body, which is subject to death, the Guru's compassion is greater because He removes the very cycle of birth and death. As mentioned in the chapter, this is the Guru's "additional compassion," highlighting their unique and essential role in a devotee's spiritual liberation.
