What are the 'nooses of death' and how does one enter the 'heavenly world' according to this scripture?

Based on the teachings in Chapter 37, the 'nooses of death' are not physical but are identified as Adharma (unrighteousness), ignorance, anger, and hatred. A person who manages to cross beyond these entirely is said to enter the heavenly world. This heavenly world is not a physical place but is described as the Vairaj (the Cosmic Being) itself. It is a state of consciousness where there is no cause for disease, worry, illness, or sorrow, and no fear of death. It is a state of non-duality, where the soul can move about completely fearless. Therefore, entering heaven is about transcending negative qualities and achieving a higher state of being.
