Why does the author of Chapter 49 describe Sai's 'Leela' and greatness as inexpressible?

In Chapter 49, the author emphasizes the profound difficulty in capturing the essence of Sai's greatness through words. He states that the Sadguru's 'Leela' (divine play) is "inexpressible" and his own speech cannot adequately describe it. The author posits, "How can I comprehend the inconceivable art of the Unfathomable?" The text further explains this limitation by referencing the different stages of speech, noting that where the transcendental (Para), and even the middle stages (Pashyanti, Madhyama), do not venture, the spoken word (Vaikhari) is utterly powerless. This illustrates that Sai's nature transcends the limits of human language and comprehension.
