The text mentions 'nooses of death' and the cycle of Samsara. What are these, and how does one become subject to them?

Chapter 37 explains that 'adharma (unrighteousness), ignorance, anger, and hatred' are the true nooses of death. A person becomes subject to the eternal cycle of worldly existence, or Samsara—where death follows birth and rebirth follows death—due to a fundamental ignorance. This ignorance is the delusion of difference, the belief that 'Parabrahman is different from me; I am not that.' As the chapter states, he who has this knowledge of separation is always subject to death. Escaping this cycle involves crossing over these negative qualities and realizing the oneness of the Self with the divine principle.
