What is the crucial difference between verbal knowledge and direct experience as it relates to being a Sadguru in Chapter 48?

Chapter 48 draws a sharp distinction between verbal knowledge and direct experience. It describes verbal knowledge without self-experience as "verbally hollow," even if the explanations are sweet and the knowledge seems vast. The chapter emphasizes that the "taste of experience is pure," and only a person who has this direct experience can truly manifest it and guide others. According to the teachings in Chapter 48, a person who does not have experience themselves has nothing to give a disciple. Therefore, the authority to be a Sadguru rests solely with one who combines complete verbal knowledge with the ability to give direct, full experience.
