According to the philosophy in Chapter 37, what is the true nature of heaven, and why is it considered an unworthy goal compared to Self-realization?

Chapter 37 presents a radical reinterpretation of heaven. It argues that the conventional heavenly abode, attained through sacrifices and penance, is merely a place for sensual enjoyment and is ultimately useless if it lacks the remembrance of God. The chapter defines true heaven as the realization of the Vairaj, the Cosmic Being or Self-form, which is a state completely free from mental grief, disease, worry, hunger, or the fear of death. This divine heavenly state is one where the soul moves about fearlessly. Therefore, seeking a temporary abode for sensory pleasure is misguided when one can attain the eternal, all-pervading principle of Brahman that exists equally here and in the hereafter.
