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

In the teachings found within Chapter 37, the "nooses of death" are not physical but internal states: adharma (unrighteousness), ignorance, anger, and hatred. The text clarifies that one who successfully crosses beyond these negative qualities is the one who truly enters the heavenly world. This "heaven" is not a physical location but a state of being, described as the Vairaj (the Cosmic Being) itself. It is a state free from mental grief, disease, worry, sorrow, hunger, thirst, and the fear of death, where the soul can move about with complete fearlessness.
