What is the crucial difference between simple verbal knowledge and the qualities of a Sadguru as explained in Chapter 48?

Chapter 48 highlights a critical distinction between mere verbal knowledge and the essence of a Sadguru. The text describes verbal knowledge without self-experience as "verbally hollow," even if the explanations are sweet and seem correct. It asserts that the "taste of experience is pure," and only an experienced person can manifest it. As detailed in this chapter, a Sadguru is someone who possesses both complete verbal knowledge and is also a giver of direct, full experience. The chapter poses a rhetorical question: one who has no direct experience themselves, what can they possibly give to a disciple?
