Why does the author of the Sai Satcharitra find it so difficult to describe Sai Baba's greatness?

In Chapter 49, the author expresses the profound difficulty in articulating the Sadguru's greatness. He notes that even the Vedas and Puranas grew weary of this task, suggesting that silence is the most fitting praise. The author explains that Sai's divine play, or 'Leela,' is inexpressible and that his own speech cannot capture the "inconceivable art of the Unfathomable." He touches upon the limits of language, pointing out that the Guru's nature is beyond even the transcendental (Para) stage of speech, let alone the spoken word (Vaikhari), making any description inherently incomplete.
