Chapter 49 mentions different stages of speech. How does it use this concept to explain the difficulty in describing Sai Baba's greatness?

Chapter 49 uses the Vedic concept of the four stages of speech to illustrate the impossibility of describing the Sadguru. The author explains that the Guru's true nature exists where "Para," or transcendental speech, returns defeated. The chapter further notes that even the more subtle, internal stages of speech, known as "Pashyanti" and "Madhyama," cannot access this divine reality. Given that these higher forms of speech are inadequate, the text questions what the fourth and most external stage, "Vaikhari" (the spoken word), could possibly accomplish. This philosophical argument powerfully conveys that Sai Baba's essence is inexpressible and beyond the grasp of human language and intellect.
