Based on the teachings in Chapter 48, what is the crucial role of direct experience for a Sadguru?

According to the teachings presented in Chapter 48, direct experience is the most critical and non-negotiable element for a true Sadguru. The text emphasizes that while verbal knowledge can be vast and explanations sweet, it is "verbally hollow" without the backing of self-experience. A true Sadguru is defined as one who is a "giver of direct, full experience," possessing the authority to genuinely enlighten disciples. Chapter 48 makes it clear that the "taste of experience is pure," and only someone who has this direct, personal realization can manifest it for others. The chapter ultimately posits that a person without experience has nothing to give a disciple.
