Based on Chapter 28, what is the nature of Sai as a Sadguru and his relationship with his devotees?

Chapter 28 explains that Sai Baba is a true Sadguru because he is proficient in both Shabda-Brahma (the divine word) and shows the signs of Para-Brahman (the Supreme Being). He is not separate from anyone, dwelling in all beings from the highest to the smallest insect. The chapter distinguishes a Guru's compassion from a father's love, noting that while a father gives birth to a body that will eventually die, a Guru has the power to remove the entire cycle of birth and death. Furthermore, it states that when the karma of many births ripens, a person attains the company of a saint like Sai, which ignites discrimination and destroys delusion, leading to a successful life.
