Can you explain the concept of the limitations of speech as described in Chapter 49 when trying to comprehend the Sadguru?

Chapter 49 delves into the profound inadequacy of human language to describe the Sadguru's true nature. The author explains that the "Para" or transcendental speech returns from the attempt, unable to grasp the Unfathomable. The text mentions different stages of speech, noting that even Pashyanti and Madhyama (subtler, middle stages) cannot approach this reality, let alone the fourth stage, Vaikhari, which is the spoken word. The author acknowledges this limitation completely but still feels compelled to write. The chapter suggests that true understanding comes not from words but from surrendering at the Sadguru's feet to receive His grace.
