What specific characteristics and behaviors of Sai Baba are highlighted in Chapter 37 that make his actions 'incomprehensible and marvelous'?

Chapter 37 describes Sai Baba's actions as 'incomprehensible and marvelous' by detailing his unpredictable and profound nature. It notes his varied states: sometimes he was 'intoxicated with Brahmananda (the bliss of the Self),' and at other times he was 'satisfied with Self-knowledge' or performed actions while remaining completely detached. The chapter explains that while he could appear devoid of activity, he was never asleep but always alert and fixed on Self-realization. His character is likened to the deep and unfathomable ocean. Adding to this mystique was his universally known celibacy and his familial treatment of all people, viewing men as brothers and women as sisters or mothers, as this chapter narrates.
