What is the central theme discussed in Chapter 48 of the Sai Satcharitra?

Chapter 48 of the Sai Satcharitra addresses a listener's profound question: 'Is Shri Sai a Guru or a Sadguru?' The central theme is to define the characteristics of a true Sadguru, distinguishing them from other teachers. The chapter explains that a Sadguru is not merely someone with scriptural knowledge or one who performs specific practices. As the text clarifies, a true Sadguru is one who possesses both profound verbal knowledge and, most importantly, direct self-experience, making them uniquely qualified to guide a disciple towards enlightenment. The entire chapter is dedicated to outlining these essential qualities.
