Chapter 48 contrasts verbal knowledge with direct experience. Can you elaborate on how the text develops this distinction to define a true Sadguru?

In Chapter 48, the distinction between verbal knowledge and direct experience is central to defining a Sadguru. The text describes teachers who possess vast verbal knowledge and deliver sweet explanations of principles but lack self-experience, rendering their knowledge 'verbally hollow.' While their words might create a temporary distaste for worldly enjoyments, the chapter notes that only an experienced person can manifest the 'pure taste of experience.' It asserts that a true Sadguru is one who not only has complete verbal knowledge but is also a 'giver of direct, full experience,' which grants them the authority to enlighten disciples.
