Chapter 49 mentions the four stages of speech (Para, Pashyanti, Madhyama, Vaikhari). How does the text use this concept to explain the nature of the Sadguru?

Chapter 49 employs the Vedic concept of the four stages of speech to illustrate the sheer inexpressibility of the Sadguru's greatness. The author states that Sai's Leela is so profound that even 'Para,' the highest, transcendental form of speech, returns from it, unable to grasp or describe it. Because Para speech fails, the subsequent, more subtle stages of 'Pashyanti' and 'Madhyama' are not even mentioned. This leads to the rhetorical question of what the fourth and most manifest stage, 'Vaikhari' (the spoken word), could possibly accomplish. By using this powerful analogy, Chapter 49 makes it clear that the Sadguru's true form and glory are beyond the limits of human intellect and language.
