Can you summarize the key messages and descriptions of Sai Baba found in Chapter 37?

Chapter 37 presents a profound description of Sai Baba, portraying his life story and daily actions as blessed, marvelous, and ultimately incomprehensible. The chapter highlights his unpredictable state, sometimes appearing intoxicated with divine bliss and at other times completely detached. It emphasizes his strict celibacy and how he treated men with brotherhood and women as his sisters or mothers. Furthermore, the chapter delves into a philosophical discourse, redefining concepts like death and heaven, suggesting that true heaven is a state of Self-realization, not a physical realm for sensual pleasure. The text explains that what we call death is merely the manifest form returning to the unmanifest.
