How does Chapter 37 redefine the concept of 'heaven' and contrast it with the conventional understanding of a place for sensual enjoyment?

Chapter 37 presents a sophisticated reinterpretation of heaven. It dismisses the conventional heavenly abode, attained through sacrifices, as merely a place for sensual enjoyment that is useless if it lacks the remembrance of God. Instead, the chapter defines the true heavenly state as the Vairaj, or the Cosmic Self-form. This is a state of being, not a place, where one is free from all grief, disease, worry, and the fear of death. As described in Chapter 37, this divine state is achieved by crossing over the 'nooses of death' like ignorance and anger.
