Based on the provided text, what is the definition of death and what are the real 'nooses of death' that bind a person?

According to the insights in Chapter 37, 'death' is described as the process by which something in a manifest state returns to the unmanifest. However, the text emphasizes that the true spiritual dangers are the 'nooses of death,' which it identifies as Adharma (unrighteousness), ignorance, anger, and hatred. It is stated that only the person who completely crosses beyond these negative qualities can truly enter the heavenly world, implying that this spiritual transcendence is more significant than the physical act of dying.
