How is the concept of 'heaven' reinterpreted in Chapter 37, and why is it considered less desirable than life on earth?

Chapter 37 presents a profound reinterpretation of heaven, moving beyond a mere location for sensual pleasure. It defines the true heavenly state as the Vairaj (the Cosmic Being) itself, a state of being where one beholds the Cosmic Self-form, free from all mental grief, disease, worry, or fear of death. However, the text argues that a heavenly abode attained through merit is temporary, as one falls from it once the merit is exhausted. It is criticized as a place for sensual enjoyment, which is equated to the pleasure a donkey finds in a dung-heap. Therefore, as explained in Chapter 37, birth on earth is considered of profound importance because even a fleeting life, when its actions are offered to God, can lead to the ultimate state of fearlessness, which is superior to the transient pleasures of heaven.
