What is the philosophical explanation of death and the 'nooses of death' as presented in Chapter 37?

In Chapter 37, death is philosophically defined not just as a physical end but as the transition of a being from its manifest state back into the unmanifest. The text goes on to identify what it calls the 'nooses of death,' which are not physical but spiritual and psychological obstacles. These are listed as Adharma (unrighteousness), ignorance, anger, and hatred. The chapter suggests that one who can entirely cross beyond these nooses is the one who truly enters the heavenly world, transcending the cycle of rebirth. This perspective shifts the focus from physical demise to spiritual liberation.
