Chapter 48 emphasizes the concept of 'self-experience' for a Sadguru. Can you elaborate on why this is considered the most critical quality for a true spiritual master?

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 without this direct, personal realization, any knowledge, however vast or sweetly explained, is merely "verbally hollow." It poses the rhetorical question: "One who does not have experience himself, what will he give to the disciple?" This implies that spiritual transmission is impossible without the master's own attainment. The chapter clarifies that while intellectual explanations might create a temporary distaste for worldly things, only the "taste of experience" is pure and can be manifested by an experienced person. Therefore, the ability to grant a disciple "direct, full experience" is what separates a true Sadguru from a mere scholar.
