According to the teachings in Chapter 37, what is the true nature of heaven and how does it differ from the common perception?

Chapter 37 presents a philosophical reinterpretation of heaven, moving away from the idea of a physical place for sensual enjoyment. It defines the true heavenly world as the Vairaj, or the Cosmic Being's Self-form, which is a state of consciousness free from mental grief. As detailed in this chapter, this heavenly state is characterized by the absence of disease, worry, sorrow, hunger, thirst, old age, and the fear of death. It is a state of non-duality where the soul moves fearlessly. The text explicitly questions the desire for a heaven attained through rituals, calling it merely a place for sensual pleasure and useless if it lacks the remembrance of God.
