What is the text's perspective on death and the concept of heaven?

According to the teachings in Chapter 37, what we call 'death' is simply the manifest form returning to its unmanifest state. The true "nooses of death" are identified as unrighteousness (Adharma), ignorance, anger, and hatred. The text redefines heaven, not as a physical place for sensual enjoyment, but as the state of realizing the Cosmic Self-form, which is free from mental grief, disease, worry, and the fear of old age or death. This divine heavenly state is one where the soul moves about completely fearless, transcending the duality of 'do's and don'ts'.
