The Shri Sai Satcharitra describes Sai's state as 'unpredictable' and 'incomprehensible'. Can you explain what this means based on the text?

Chapter 37 of the Shri Sai Satcharitra describes Sai Baba's state as unpredictable and marvelous, truly beyond description. His actions are often incomprehensible to the observer. The text explains that He could be seen in various states: sometimes intoxicated with the bliss of the Self (Brahmananda), other times perfectly content with His Self-knowledge. He could also be performing many actions while remaining completely detached internally. There were times He appeared devoid of all activity, yet He was not asleep but was always alert, with His mind fixed on Self-realization in His own true form. This multifaceted and profound nature is why the chapter states that His unfathomable form is difficult to truly describe.
