What is the significance of 'self-experience' in a Sadguru as explained in Chapter 48?

According to Chapter 48, self-experience is the most critical attribute of a Sadguru, distinguishing them from those with only verbal knowledge. The text states that while explanations of principles can be sweet and verbal knowledge vast, it is 'verbally hollow' without the backing of self-experience. It poses a rhetorical question: 'One who does not have experience himself, what will he give to the disciple?' Therefore, this chapter establishes that a true Sadguru is one who not only possesses complete knowledge but is also a 'giver of direct, full experience,' as only an experienced person can manifest the pure taste of that experience for others.
