Can you describe the nature and actions of Sai Baba as explained in the text?

Chapter 37 describes Sai Baba's nature as incomprehensible, marvelous, and truly beyond description. His actions are profound, and He is sometimes seen as intoxicated with the bliss of the Self (Brahmananda) or satisfied with Self-knowledge. While performing everything, He remains detached. He is always alert in His true form, keeping His mind fixed on Self-realization. The text also highlights His character, noting that He holds brotherhood with men and treats women as His sisters or mothers, being a celibate known to all.
