According to the provided text, what is the role of speech in praising the Sadguru, and what are its limitations?

In Chapter 49, the role of speech is presented as limited yet necessary. The author states that while "maintaining silence is the real praise of the Sadguru," the beauty of Sai's Leela compels him to speak. The limitations of language are explained by referencing the four stages of speech, noting that where Para, Pashyanti, and Madhyama (the transcendental and middle stages) do not function, the fourth stage, Vaikhari (the spoken word), is also inadequate. This section of Chapter 49 illustrates that the Sadguru's greatness is beyond human description, even though the heart desires to express it.
