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

Chapter 28 explains that a true Sadguru, like Sai Baba, is established in their own true nature and possesses the ability to impart teachings to disciples. The chapter highlights that Sai is proficient in both Shabda-Brahma (the divine word) and shows the signs of Para-Brahman (the Supreme Being), which are qualities of a Sadguru. Furthermore, the text contrasts a father, who gives birth to a body subject to death, with the Guru, who offers greater compassion by removing the cycle of both birth and death for the devotee. As Chapter 28 states, this illustrates the profound spiritual role of the Sadguru.
