How does the text define death, and what are considered the 'nooses of death'?

Chapter 37 explains death as the process by which something that has come into form from the unmanifest returns to the unmanifest again. This is what people commonly call 'death'. The text further identifies specific spiritual and moral failings as the 'nooses of death'. These are explicitly listed as adharma (unrighteousness), ignorance, anger, and hatred. The chapter suggests that one who successfully crosses these nooses on their own can enter the heavenly world.
