What are the 'nooses of death' mentioned in the text, and what is described as the true 'heavenly world' that one can enter?

The text identifies the 'nooses of death' as Adharma (unrighteousness), ignorance, anger, and hatred. Chapter 37 explains that a person who can cross these obstacles entirely on their own is the one who enters the heavenly world. This heavenly world is not a physical place but a state of being. It is described as the Vairaj (the Cosmic Being) itself, a Virat (Cosmic) Self-form free from mental grief. In this divine heavenly state, there is no disease, worry, illness, or sorrow. One is not afflicted by hunger, thirst, the fear of old age, or the fear of death, and the soul can move about completely without fear, free from the duality of 'do's and don'ts'.
