What is the philosophical definition of 'death' and the 'heavenly world' as explained in the Satcharitra?

Chapter 37 offers a profound perspective, defining death as the process by which something that has come into form from the unmanifest returns to the unmanifest state. It further identifies the real 'nooses of death' as unrighteousness, ignorance, anger, and hatred. The 'heavenly world' is not a physical place for sensual enjoyment but is described as the Vairaj (the Cosmic Being) itself. This divine heavenly state is one free from mental grief, disease, worry, hunger, thirst, or fear of death, where the soul can move about completely fearless. This state is achieved by crossing beyond the spiritual failings that constitute the nooses of death.
