Chapter 49 mentions different types of speech like 'Vaikhari' and 'Para'. What is it trying to convey about the nature of Sai Baba and the limits of language?

Chapter 49 uses the concepts of different stages of speech to illustrate the transcendental and inexpressible nature of the Sadguru, Sai Baba. The author explains that his speech cannot describe Sai's 'inconceivable art.' He references how 'Para' (transcendental speech) returns, and how 'Pashyanti' and 'Madhyama' (subtler stages of speech) cannot even begin to describe Him. This leads to the conclusion that 'Vaikhari' (the spoken word), the fourth and most gross form of speech, is utterly incapable of the task. The core message here, as presented in Chapter 49, is that the Guru's true form is beyond intellectual comprehension and linguistic description. True realization does not come from words but from complete surrender at the Sadguru's feet, which is the only way to receive the grace necessary for understanding.
