What are the key characteristics and behaviors of Sai Baba as described at the beginning of Chapter 37?

The beginning of Chapter 37 paints a picture of Sai Baba as a truly blessed and enigmatic figure whose actions are 'incomprehensible and marvelous.' It describes his unpredictable state, noting that he is sometimes intoxicated with Brahmananda (the bliss of the Self) and at other times appears completely detached while performing actions. Despite seeming inactive, he is always alert and fixed on Self-realization. The chapter highlights his profound nature, comparing him to a deep and difficult-to-fathom ocean. Furthermore, as Chapter 37 details, it emphasizes his personal conduct, stating he holds brotherhood with men and treats all women as his sisters or mothers, living as a celibate known to all.
