How does Chapter 48 differentiate between a teacher with mere verbal knowledge and a true Sadguru who can provide genuine experience?

In Chapter 48, a clear distinction is made between a teacher with only verbal knowledge and an authentic Sadguru. While a knowledgeable person's explanations may sound sweet and correct, leading one to feel distaste for worldly enjoyments, their knowledge is described as "verbally hollow" because it lacks the backing of self-experience. In contrast, a true Sadguru is defined as one who not only possesses complete verbal knowledge but is also a giver of direct, full experience. As the chapter explains, only an experienced person can manifest the "taste of experience," and someone who has no direct experience themselves has nothing substantial to give to a disciple.
