Can you provide a summary of the main themes discussed in Chapter 37?

Chapter 37 begins by extolling the blessed and incomprehensible nature of Sai Baba's life, describing him as sometimes intoxicated with divine bliss and at other times completely detached. The chapter explains his treatment of men as brothers and women as sisters or mothers, highlighting his celibacy. It then transitions into a philosophical discussion on the nature of death and heaven. As detailed in this chapter, death is not just a physical event but a transition from the manifest to the unmanifest, with unrighteousness, ignorance, anger, and hatred acting as the 'nooses of death.' The text defines the true heavenly state not as a physical place but as a state of consciousness free from suffering and fear, which is the Cosmic Self-form itself.
