What is the concept of 'heaven' as described in Chapter 37, and how does it contrast with a place of sensual enjoyment?

Chapter 37 presents a nuanced and spiritual definition of heaven, contrasting it sharply with the common idea of a place for sensual pleasure. The text posits that the true heavenly world is the Vairaj, or the Cosmic Being itself. This divine heavenly state is characterized as a reality where there is no cause for disease, worry, illness, or sorrow. In this state, one is not afflicted by hunger, thirst, or the fear of old age or death. It is a realm of fearlessness where the soul can move freely without the duality of 'do's and don'ts'. Chapter 37 explicitly criticizes the desire for a heaven attained through sacrifices and penance if it lacks the remembrance of Lord Narayana, dismissing such a place as merely a hub for sensual enjoyment and questioning its value if there is no chanting of God's name.
