I'm trying to understand Sai's nature. The text says he is 'incomprehensible and marvelous.' Can you explain what this means based on Chapter 37?

Chapter 37 beautifully illustrates the enigmatic and profound nature of Sai Baba. It describes His daily life and actions as 'incomprehensible and marvelous, truly beyond description.' His state was unpredictable; He was sometimes seen intoxicated with the bliss of the Self (Brahmananda), and at other times, He appeared completely detached while performing actions. He could seem inactive, yet He was always alert and fixed on His own Self-realization. The text compares Him to the ocean—pleasant but also deep, profound, and difficult to fathom. This suggests that His true form cannot be accurately described or understood through ordinary intellect.
