Chapter 48 lists several things that do NOT automatically make someone a Sadguru. What are these misleading characteristics?

In response to a listener's query, Chapter 48 of the Sai Satcharitra outlines several characteristics that, on their own, do not qualify someone as a Sadguru. The text cautions against being misled by superficial qualities. For instance, the wise do not consider someone a Sadguru simply because they have studied the Vedas or the six Shastras. Similarly, practices like breath control (Pranayama), wearing heated marks (Taptamudra), or merely giving pleasing talks about Brahman are not definitive signs. Chapter 48 further notes that giving out mantras from scriptures without the guru having direct experience themselves is a hollow practice, as the knowledge lacks the essential taste of personal realization.
