Chapter 37 contrasts the common idea of heaven with a different spiritual understanding. Can you elaborate on the chapter's definition of the true 'heavenly world'?

Chapter 37 redefines heaven, dismissing the conventional notion of a place for sensual enjoyment attained through rituals. Instead, it posits that the true heavenly world is the Vairaj, the Cosmic Being itself. This is described as a state of being, the Virat (Cosmic) Self-form, which is free from mental grief. As detailed in the chapter, this divine heavenly state is one where there is no disease, worry, illness, sorrow, hunger, thirst, or fear of old age and death. It is a state of non-duality where the soul moves about completely fearless, a concept far removed from a heavenly home that lacks the remembrance of God's name.
