What are the characteristics of a Sadguru's environment and their personal demeanor as mentioned in Chapter 48?

Chapter 48 of the Shri Sai Satcharitra provides a description of a Sadguru's nature and the atmosphere they create. A key characteristic is the absence of ego; there should be no pride in scholarship, and they must treat the small and the great as equals. Their dwelling place is described as a "storehouse of supreme peace." A true Sadguru is a benefactor who is free from the egoism that elevates the Guru above the disciple and instead holds a fatherly love for them, viewing them as the Supreme Brahman.
