Chapter 48 of Sai Satcharitra begins by addressing a listener's question about whether Sai is a Guru or a Sadguru. What specific traits does the chapter say should NOT be mistaken for the signs of a Sadguru?

To clarify the signs of a Sadguru, Chapter 48 lists several attributes that do not qualify someone for this title. The chapter states that wise men do not call those Sadgurus who merely obtain knowledge from the Vedas or Shastras, or who can explain Vedanta. Similarly, performing practices like breath control (Pranayama), wearing heated marks (Taptamudra), or delivering pleasing talks about Brahman are not sufficient. The text cautions against those who give mantras from scriptures but cannot guarantee the fruit of the practice, as their knowledge is purely verbal and lacks the essential self-experience that a true Sadguru must possess.
