Can you explain the concept of the limitations of speech as discussed in Chapter 49 of the Sai Satcharitra?

Chapter 49 delves into the inadequacy of language to describe the divine. The author explains that when trying to sing the Sadguru's unfathomable greatness, even the highest forms of speech fall short. The text specifically mentions that the "Para (transcendental) speech returns from" this endeavor, and there is no mention of "Pashyanti or Madhyama," which are subtler stages of speech. This implies that if these higher, more refined forms of speech cannot grasp the reality of the Sadguru, the fourth and most gross form, "Vaikhari (spoken word)," is certainly incapable of doing so. This philosophical point underscores the transcendent and inexpressible nature of Sai Baba.
