Based on the text from Chapter 48, why is 'self-experience' considered the most crucial attribute of a Sadguru?

In Chapter 48, 'self-experience' is presented as the cornerstone of a true Sadguru because it is the source of their ability to guide others authentically. The text argues that verbal knowledge without experience is "verbally hollow." It poses a rhetorical question: "One who does not have experience himself, what will he give to the disciple?" This highlights the core teaching that only an experienced person can manifest the pure "taste of experience" for others. Therefore, as this chapter explains, a Sadguru's authority to enlighten disciples comes from being a "giver of direct, full experience," a quality that cannot be faked or replaced by mere scholarly knowledge.
