What are the main teachings and stories in Chapter 48 of Sai Satcharitra?

The primary teaching of Chapter 48 of the Shri Sai Satcharitra is to define the characteristics of a true Sadguru, prompted by a listener's question about whether Shri Sai is a Guru or a Sadguru. The chapter explains that a Sadguru is not defined by mere scriptural knowledge, the ability to explain Vedanta, or practices like Pranayama. Instead, as detailed in Chapter 48, a true Sadguru is one who possesses direct, full self-experience and has the authority to impart that experience to their disciples. This chapter emphasizes that a Sadguru is free from ego, views the disciple as a form of the Supreme Brahman with fatherly love, and is willing to sacrifice for the disciple rather than seek service from them. The dwelling of a Sadguru is described as a 'storehouse of supreme peace' where everyone is treated equally.
