How does Chapter 49 describe the challenge of capturing the Sadguru's greatness in words?

Chapter 49 portrays the greatness of the Sadguru as fundamentally inexpressible. The author begins by stating that the Vedas and Puranas grew weary of this task. He refers to the four stages of speech, noting that where the highest, Para (transcendental) speech, returns defeated, the other stages like Pashyanti and Madhyama cannot tread. Consequently, the fourth stage, Vaikhari (the spoken word), is utterly powerless to describe the Guru's unfathomable nature. The author concludes that without surrendering at the Sadguru's feet, one cannot grasp the true form, highlighting that the Guru's essence is beyond the limits of human intellect and language.
