What is the philosophical definition of 'death' and the 'nooses of death' provided in this text?

The text offers a unique perspective on mortality. According to Chapter 37, what we call 'death' is merely the transition of a form that came from the unmanifest returning to the unmanifest state. It is not an end but a part of a cycle. The true obstacles, or 'nooses of death,' are identified as adharma (unrighteousness), ignorance, anger, and hatred. The passage suggests that one who can entirely cross these internal negativities is the one who truly enters the heavenly world, transcending the conventional fear of death.
