What does the text say about the concepts of life, death, and the 'nooses of death'?

Chapter 37 explains that what we call the 'manifest' state is that which comes into form from the unmanifest. When this form enters the unmanifest again, it is called 'death'. The text further elaborates on the true obstacles to spiritual liberation, referring to them as the 'nooses of death.' These are not physical but internal states: Adharma (unrighteousness), ignorance, anger, and hatred. It is only by completely crossing these obstacles that one can enter the heavenly world, suggesting that true death is being bound by these negative qualities, while overcoming them is a form of spiritual transcendence.
