According to the philosophy in Chapter 37, what is the true nature of 'heaven' and 'death'?

Chapter 37 presents a profound philosophical perspective on heaven and death. It explains that what is commonly called 'death' is merely the transition of a manifest form back into the unmanifest state. The true 'nooses of death' are identified as adharma (unrighteousness), ignorance, anger, and hatred. Conversely, heaven is not a physical place for sensual enjoyment but a state of being. As described in Chapter 37, heaven is the Vairaj, the Cosmic Self-form, a state free from disease, worry, sorrow, hunger, and the fear of death or old age. This divine heavenly state is one of fearlessness and non-duality, where the soul moves about completely fearless.
