What are the defining qualities of a true Sadguru and their dwelling place as outlined in Chapter 48 of the Sai Satcharitra?

Chapter 48 of the Sai Satcharitra outlines several key qualities of a true Sadguru. A Sadguru is defined not by scriptural knowledge or giving mantras alone, but by being a giver of direct, full experience. They are selfless, wishing to sacrifice for their disciple rather than receive service. A Sadguru is free from ego, has fatherly love for the disciple, and treats everyone equally. As Chapter 48 describes, the place of a Sadguru is a "storehouse of supreme peace," where there is no pride in scholarship and where both the small and the great are treated as equals.
