According to Chapter 49, why is it so difficult to describe the Sadguru, and what is considered the truest form of praise?

Chapter 49 explains that the Sadguru's greatness is so vast that even the Vedas and Puranas grew weary of praising him. The author states that his true Leela (divine play) is inexpressible and his art is inconceivable, to the point where even different forms of speech cannot capture his essence. Because of this, the chapter suggests that maintaining silence is actually the real and truest form of praise for the Sadguru. However, the author also notes that the qualities of Sai are so compelling that they make him forget this silence and feel compelled to share these stories.
