According to Chapter 49, why is it so difficult to describe the greatness of a Sadguru like Sai Baba?

Chapter 49 explains that describing the Sadguru's greatness is a nearly impossible task, as even the Vedas and Puranas grew weary of this effort. The author notes that the Sadguru's leela is inexpressible and His art is inconceivable. The text delves into the theory of speech, stating that the highest form, Para (transcendental speech), returns from the attempt, and the lower forms like Vaikhari (spoken word) are wholly inadequate. While acknowledging that silence is the real praise, the author is compelled to write because the bliss of Sai's qualities is too profound to keep to oneself, much like a sweet delicacy one must share.
