According to the text, what are the "nooses of death," and how does one overcome them to reach the "heavenly world"?

Chapter 37 explicitly identifies the "nooses of death" as Adharma (unrighteousness), ignorance, anger, and hatred. It is not physical cessation but these negative qualities that bind a soul. The text states that a person who manages to cross these obstacles entirely is the one who truly enters the heavenly world. This "heavenly world" is described not as a physical location but as a state of being—the realization of the Vairaj (the Cosmic Being). This state is characterized by the complete absence of mental grief, disease, worry, sorrow, and the fear of death.
