What is the nature of a Sadguru as described in the beginning of Chapter 28?

The beginning of Chapter 28 describes the profound nature of a Sadguru like Sai Baba. It states that a Sadguru is proficient in both Shabda-Brahma (the divine word) and shows signs of Para-Brahman (the Supreme Being). A Sadguru has the ability to impart teaching to disciples. Furthermore, the chapter contrasts a father who gives birth to a body subject to death, with a Guru who compassionately removes both birth and death for the devotee. This highlights the Sadguru's role in spiritual liberation, a quality that belongs to one established in their own true nature.
