What are the primary characteristics of a true Sadguru as described in Chapter 48 of the Sai Satcharitra?

According to Chapter 48 of the Sai Satcharitra, a true Sadguru possesses several key characteristics that distinguish them. A Sadguru is one who not only has complete verbal knowledge but is also a giver of direct, full experience, which is the authority to enlighten disciples. They are free from the egoism of seeing themselves as superior to the disciple. Instead, a Sadguru considers the disciple as the Supreme Brahman and holds a fatherly love for them. As the chapter further details, they are selfless, wishing to sacrifice for the disciple rather than receiving service, and their abode is a place of supreme peace where all are treated as equals.
