How does Chapter 48 distinguish between a genuine Sadguru and someone who only possesses theoretical knowledge?

In Chapter 48 of the Sai Satcharitra, the distinction between a genuine Sadguru and a mere scholar is centered on self-experience. The text describes those with only vast verbal knowledge as "verbally hollow," even if their explanations seem right and sweet. It explicitly states that wise men do not call them Sadgurus. A true Sadguru, according to this chapter, is one who not only has knowledge but is also a "giver of direct, full experience." The ability to manifest this pure taste of experience is what grants them the authority to enlighten disciples, a capacity that someone without personal experience lacks.
