What are some of the qualities and attitudes that, according to the text, do NOT make someone a Sadguru?

The beginning of Chapter 48 clearly lists several qualities that are insufficient for one to be considered a Sadguru. The wise do not confer this title upon those merely for their study of the Vedas or six Shastras, or their ability to explain Vedanta. Furthermore, practices like breath control (Pranayama), wearing heated marks (Taptamudra), or simply pleasing an audience with talks about Brahman are not the signs of a true Sadguru. The chapter critiques those whose knowledge is vast but lacks the crucial element of self-experience.
