How does Chapter 49 explain the difficulty of describing Sai Baba's greatness through language?

Chapter 49 explains that describing the Sadguru's greatness is an impossible task for speech. The author notes that even the Vedas and Puranas grew weary in their attempts to praise the Sadguru, suggesting silence is the most fitting tribute. The text delves into the philosophy of speech, mentioning that where the transcendental (Para) and middle stages (Pashyanti, Madhyama) of speech cannot reach, the fourth stage, the spoken word (Vaikhari), is utterly powerless. This illustrates that Sai's 'Leela' is inexpressible and His art is inconceivable, far beyond the grasp of human language.
