What were the characteristics of Sai Baba's incomprehensible nature as portrayed in the Satcharitra?

Chapter 37 describes Sai Baba's daily life and actions as incomprehensible, marvelous, and truly beyond description. His state was unpredictable; sometimes He appeared intoxicated with Brahmananda (the bliss of the Self), and at other times, He was perfectly content with Self-knowledge. He could perform all worldly actions while remaining internally detached. Though He might appear inactive, He was always alert, with His mind fixed on Self-realization. His nature is compared to the ocean: pleasant and inviting on the surface, yet immeasurably deep, profound, and ultimately unfathomable to the ordinary mind.
