Chapter 49 mentions different stages of speech like 'Vaikhari'. What is the author trying to say about the limitations of language when describing Sai Baba's greatness?

In Chapter 49, the author uses the concept of the four stages of speech from Hindu philosophy to explain the inadequacy of language in capturing the Sadguru's true nature. He states that Sai's divine play is inexpressible and His art is inconceivable. He notes that the highest, transcendental form of speech (Para) turns back, unable to describe Him. Even the subtler stages, Pashyanti and Madhyama, fail to articulate His glory. The implication is that if these higher forms of speech are insufficient, then the fourth and most common form, Vaikhari (the spoken word), is utterly powerless to do so. This philosophical point emphasizes that the Unfathomable nature of Sai Baba is beyond verbal description and can only be truly understood through surrender and grace.
