How does Chapter 49 explain the incomprehensible nature of Sadguru Sai Baba, particularly in relation to the limits of speech?

Chapter 49 emphasizes that the Sadguru's greatness is beyond human comprehension and expression. The author begins by stating that even the Vedas and Puranas grew weary of praising the Sadguru, suggesting that silence is the most fitting tribute. The text explains that Sai's 'Leela' (divine play) is inexpressible and his art is inconceivable. It delves into the philosophy of speech, noting that where transcendental speech ('Para') returns, the subsequent stages of 'Pashyanti' and 'Madhyama' have no place. This makes it impossible for the final stage, the spoken word ('Vaikhari'), to describe the Sadguru's true nature. This illustrates that Sai's essence exists beyond the highest forms of human and even divine articulation.
