In Chapter 48, why is 'direct, full experience' considered more vital for a Sadguru than extensive verbal or scriptural knowledge?

Chapter 48 posits that 'direct, full experience' is the most critical attribute of a Sadguru, superseding all other qualifications. The text argues that while extensive verbal knowledge may sound sweet and scriptural explanations may seem right, they are ultimately "verbally hollow" without personal realization. The chapter states that one who does not have experience themselves cannot possibly give it to a disciple. It suggests that while intellectual understanding might create a temporary distaste for worldly enjoyments, only the "taste of experience is pure." Therefore, as Chapter 48 concludes, the authority to truly enlighten disciples belongs exclusively to the Sadguru who can give this direct, full experience.
