Explain the philosophical concept of the limitations of speech as described in Chapter 49 in the context of praising the Sadguru.

Chapter 49 delves into the inadequacy of language to capture the Sadguru's unfathomable nature. The author explains that Sai's Leela is inexpressible. To illustrate this, the chapter references the Vedic theory of speech, noting that even the highest form, Para (transcendental speech), "returns" without being able to describe His greatness. The text continues by stating that the subsequent stages, Pashyanti and Madhyama, also fail to "open their mouths." Therefore, the chapter rhetorically questions what the fourth and lowest stage, Vaikhari (the spoken word), could possibly accomplish, underscoring the ultimate futility of using words to comprehend the Inconceivable.
