What is the Satcharitra's perspective on the nature of Sai Baba and why is he considered difficult to understand?

Chapter 37 of the Shri Sai Satcharitra portrays Sai Baba's life and actions as incomprehensible, marvelous, and truly beyond description. His state is unpredictable; sometimes He is intoxicated with the bliss of the Self (Brahmananda), and at other times He is satisfied with Self-knowledge, performing all actions while remaining detached. He is described as being pleasant like the ocean, yet equally difficult to fathom, deep, and profound. The text notes that those who try to search for the cause behind each of His actions eventually become exhausted and can only sit quietly in amazement, as His true form is unfathomable.
