Based on Chapter 37, what is the true nature of heaven, and why is the conventional idea of it questioned?

Chapter 37 presents a philosophical reinterpretation of heaven, defining it not as a physical place but as a state of being. It is described as the 'Vairaj' (the Cosmic Being) or the 'Virat' (Cosmic) Self-form, a state entirely free from mental grief, disease, worry, and the fear of death or old age. In this true heavenly state, the soul is fearless. The chapter explicitly questions the desire for a conventional heaven attained through difficult sacrifices and penance, dismissing it as merely a place for sensual enjoyment. The text argues that if a place lacks the remembrance and chanting of God's name, it is of no use, making the spiritual state of being far more valuable than a location of pleasure.
