Chapter 49 mentions that Sai's greatness is beyond different stages of speech. What does this mean?

Chapter 49 explains that the greatness and 'Leela' (divine play) of Sai Baba are inexpressible and beyond human comprehension. To illustrate this, the author refers to the different stages of speech in Hindu philosophy: Para (transcendental), Pashyanti, and Madhyama (middle stages). The text states that even these subtle, internal forms of speech 'return from' the attempt to describe the Sadguru. If these higher forms of speech fail, the author questions the capacity of the fourth stage, Vaikhari (the spoken word), to do so. This philosophical reference serves to emphasize that Sai's true nature is unfathomable and cannot be captured or limited by language.
