Chapter 48 contrasts a Sadguru with other teachers. What are some of the attributes of individuals who are *not* considered Sadgurus by the wise?

In Chapter 48 of the Shri Sai Satcharitra, the author clarifies what a Sadguru is by first detailing who does not fit this description. According to the text, wise men do not consider those who simply teach the Vedas or Shastras to be Sadgurus. The chapter further explains that individuals who only practice breath control (Pranayama), wear heated marks (Taptamudra), or please audiences with talks about Brahman are not Sadgurus. Similarly, those who give mantras from scriptures but whose knowledge is verbally hollow and lacks self-experience fall short of the title of Sadguru.
