Based on Chapter 37, what is the true definition of the 'heavenly world' and how does it differ from a place of sensual pleasure?

Chapter 37 provides a profound definition of heaven, stating that it is not a mere place for sensual enjoyment but is the Vairaj (the Cosmic Being) itself. This divine heavenly state is described as the Cosmic Self-form, a condition free from mental grief, disease, worry, and the fear of old age or death. It is a state where there is no duality of 'do's and don'ts,' and the soul can move about fearlessly. The chapter explicitly dismisses the conventional heaven of sensual pleasures, questioning its use if it lacks the remembrance and chanting of God's name.
