How does Chapter 37 describe the ideal state of being that devotees should aspire to, and how does this relate to the concept of 'heaven'?

Chapter 37 redefines the concept of heaven, moving it from a distant place to an attainable state of being. The true heavenly world is described as the Vairaj, or the Cosmic Self-form, which is free from mental grief. This state is characterized by the absence of disease, worry, sorrow, hunger, thirst, or the fear of old age and death. It is a condition where the soul can move about fearlessly. The text explicitly contrasts this with the traditional view of heaven as a place for sensual enjoyment, which it deems fleeting. Devotees are encouraged to aspire to this inner state of fearlessness and unity with the cosmic principle, which pervades all of creation, rather than pursuing temporary celestial pleasures.
