What does Chapter 48 of the Sai Satcharitra say about the difference between a regular Guru and a true Sadguru?

Chapter 48 of the Sai Satcharitra draws a clear distinction between a mere Guru and a true Sadguru. It explains that wise men do not consider someone a Sadguru simply because they have studied the Vedas, can explain Vedanta, or perform practices like Pranayama. The text cautions against those with vast verbal knowledge but a "total lack of self-experience," describing their knowledge as "verbally hollow." In contrast, as detailed in this chapter, a true Sadguru is one who not only possesses complete knowledge but is also a "giver of direct, full experience." This ability to manifest the taste of experience, rather than just talk about it, is the defining characteristic of a Sadguru.
