Can you explain the importance of 'self-experience' for a Sadguru as detailed in Chapter 48?

In Chapter 48, 'self-experience' is presented as the definitive and non-negotiable trait of a Sadguru. The text argues that while verbal knowledge can be sweet and vast, it is "verbally hollow" and ultimately useless for enlightening others if it is not backed by direct experience. The chapter poses the question: "One who does not have experience himself, what will he give to the disciple?" It concludes that only an experienced person can manifest the pure "taste of experience," and therefore, only one who possesses this direct, full experience has the authority to be called a Sadguru and guide others.
