According to the scriptures, what are the 'nooses of death' and how can one overcome them to reach the heavenly world?

Chapter 37 explains that the 'nooses of death' are identified as Adharma (unrighteousness), ignorance, anger, and hatred. The text suggests that to enter the heavenly world, one must cross these obstacles entirely. This heavenly world is not just a physical place but is described as the Vairaj, the Cosmic Being itself. As detailed in Chapter 37, it is a state of being free from mental grief, disease, worry, and the fear of death, where the soul can move about without fear.
