What is the philosophical meaning of 'heaven' and 'death' as explained in the Satcharitra?

According to Chapter 37, death is understood as the process by which that which has come into form from the unmanifest returns to the unmanifest state. The true obstacles leading to spiritual death are described as the 'nooses of death': unrighteousness, ignorance, anger, and hatred. Heaven is not presented as a physical place for enjoyment but as a state of being. It is the 'Vairaj' or the Cosmic Self-form, a state free from mental grief, disease, sorrow, and the fear of old age or death. This divine heavenly state is one where the soul can move about fearlessly, having transcended duality and the nooses of death.
