Chapter 37 describes Sai Baba's state as 'unpredictable'. Can you elaborate on what this means based on the text?

Chapter 37 of the Shri Sai Satcharitra characterizes Sai Baba's state as incomprehensible and marvelous. His 'unpredictable' nature is shown in how he would sometimes be intoxicated with Brahmananda (the bliss of the Self) and at other times be perfectly satisfied with Self-knowledge. He could perform all worldly actions while remaining completely detached. The text further explains that while he might sometimes appear totally inactive, he was never asleep but was always alert, with his mind fixed on Self-realization. His state is likened to the ocean: pleasant on the surface but deep, profound, and ultimately difficult to fathom.
