Chapter 49 mentions that Sai's nature is 'inexpressible.' How does the author explain the limits of language and the right way to gain understanding?

Chapter 49 delves into the profound difficulty of describing Sai Baba's true nature using words. The author states that Sai's Leela is "inexpressible" and his speech cannot grasp the "inconceivable art of the Unfathomable." He references the philosophical concept of the four stages of speech, explaining that where the highest form of speech (Para) returns defeated, the spoken word (Vaikhari) stands no chance. Given these limitations, the chapter teaches that true understanding is not achieved through intellectual pursuit or description. Instead, it asserts that "Without surrendering at the Sadguru’s feet, the true form does not come to hand." Therefore, the path to comprehension is through complete surrender and developing love for the Guru's feet, which is called our "only true wealth."
