How does Chapter 48 differentiate between a teacher with mere scriptural knowledge and a genuine Sadguru?

Chapter 48 of the Sai Satcharitra draws a sharp distinction between a true Sadguru and a teacher who only possesses verbal or scriptural knowledge. The text states that those who merely study Vedas, explain Vedanta, or give mantras without self-experience are not considered Sadgurus. Their knowledge is described as 'verbally hollow' because they lack the direct experience necessary to enlighten a disciple. In contrast, as Chapter 48 clarifies, a genuine Sadguru is one who not only has complete knowledge but is also a 'giver of direct, full experience.' The ability to manifest this experience in a disciple is the key differentiator, making the Sadguru's guidance truly transformative.
