Based on Chapter 49, why is it so difficult to describe the greatness of the Sadguru, Sai Baba?

Chapter 49 explains that the greatness of the Sadguru, Sai Baba, is fundamentally beyond human comprehension and expression. The author states that even the Vedas and Puranas "grew weary of praising the Sadguru," suggesting that sacred scriptures themselves cannot fully capture His essence. The chapter delves into the philosophy of speech, noting that the Sadguru's nature is a realm where even the transcendental (Para), visionary (Pashyanti), and mental (Madhyama) stages of speech have no access. Therefore, the fourth stage, the spoken word (Vaikhari), is utterly incapable of describing Him. This is why the author concludes that maintaining silence is the most authentic praise, as the Sadguru's true nature is inexpressible and inconceivable.
