According to Chapter 49, what is the relationship between speech and describing the Sadguru's greatness?

Chapter 49 explains that the Sadguru's greatness is ultimately beyond description. The author notes that his speech cannot capture Sai's "inexpressible Leela" and "inconceivable art." The text delves into the limitations of language, mentioning different stages of speech like Para (transcendental), Pashyanti, Madhyama, and Vaikhari (the spoken word). It posits that where the higher, more subtle forms of speech fall silent, the spoken word (Vaikhari) is certainly insufficient. The chapter suggests that while "maintaining silence is the real praise of the Sadguru," the author is compelled by Sai's qualities to write and share the stories, unable to remain still.
