Why is 'self-experience' considered the most crucial quality for a Sadguru in Chapter 48?

In Chapter 48 of the Shri Sai Satcharitra, self-experience is presented as the cornerstone of a true Sadguru's authority. The text argues that verbal knowledge, however vast or sweetly explained, is 'verbally hollow' without the backing of direct experience. It poses a rhetorical question: 'One who does not have experience himself, what will he give to the disciple?' The chapter asserts that only an experienced person can manifest the 'pure taste of experience' and has the right to enlighten others. Therefore, someone who lacks direct personal experience should never be called a Sadguru, as they cannot impart what they do not themselves possess.
