Why is 'self-experience' so crucial for a Sadguru as explained in Chapter 48 of Sai Satcharitra?

In Chapter 48 of the Sai Satcharitra, self-experience is presented as the most critical and non-negotiable quality of a Sadguru. The chapter argues that verbal knowledge, no matter how sweet or vast, is 'verbally hollow' without the backing of direct experience. It poses the rhetorical question: 'One who does not have experience himself, what will he give to the disciple?' The text asserts that only an experienced person can manifest the 'pure taste of experience' for others. Therefore, as Chapter 48 concludes, only a master who possesses this direct, full experience has the genuine authority to enlighten disciples and can rightfully be called a Sadguru.
