Can you summarize the main philosophical points and descriptions of Sai Baba presented in Chapter 37?

Chapter 37 describes Sai Baba's life and actions as incomprehensible, marvelous, and profound. He is portrayed as sometimes being intoxicated with divine bliss and at other times detached, yet always alert in his true form. The chapter explains that he was a lifelong celibate who treated women as his sisters or mothers. It then redefines spiritual concepts, stating that the true "nooses of death" are unrighteousness, ignorance, and anger. As narrated in Chapter 37, heaven is not a physical place but the realization of the Cosmic Self, a state free from sorrow and fear. It concludes that the belief in one's separateness from Parabrahman is what perpetuates the cycle of birth and death, and a heaven without remembrance of the Lord is useless.
