How is Sai Baba's personal state and nature described in the Shri Sai Satcharitra?

In Chapter 37, Sai Baba's nature is depicted as marvelous, incomprehensible, and beyond description. His state is unpredictable and profound; He is sometimes described as being intoxicated with the bliss of the Self (Brahmananda) and at other times performing actions with complete detachment. Though He might appear inactive, He is always alert and fixed on Self-realization. The text compares Him to a deep and profound ocean that is difficult to fathom. Ultimately, those who try to understand the cause behind His actions become exhausted and can only sit quietly in amazement at His unfathomable form.
