Based on Chapter 37, what is the true definition of 'heaven' and how does it differ from the popular conception?

Chapter 37 presents a philosophical definition of heaven that contrasts with a place of mere sensual enjoyment. It states that the true heavenly world is the Vairaj (the Cosmic Being) itself, the Cosmic Self-form which is free from mental grief. This divine heavenly state is a condition where there is no disease, worry, sorrow, hunger, thirst, or fear of old age and death. In this state, the soul moves about completely fearless. The text dismisses a heaven attained through sacrifices if it lacks the remembrance of God, questioning the use of a place where Govinda's name is not chanted.
