Chapter 48 mentions that some gurus give mantras but are not Sadgurus. What is the criticism leveled against this practice in the chapter?

In Chapter 48 of the Sai Satcharitra, a critical distinction is made about the practice of giving mantras. The text explains that some individuals may give disciples mantras from the scriptures and instruct them to chant (Japa), but this alone does not qualify them as a Sadguru. The core criticism is that in such cases, "there is no certainty in anyone’s heart as to when the fruit will be attained." This is contrasted with a true Sadguru, who is described as a giver of direct and full experience. As Chapter 48 clarifies, the mechanical giving of mantras without the backing of the guru's own self-experience is considered a hollow practice.
