What are the 'nooses of death' and what is the consequence of holding dualistic beliefs?

In Chapter 37, the 'nooses of death' are identified as adharma (unrighteousness), ignorance, anger, and hatred. It is stated that only by completely crossing these can one enter the true heavenly world. The text further explains the danger of dualistic thinking. A person who believes 'Parabrahman is different from me; I am not that' is deluded by ignorance and becomes subject to death. This knowledge of difference, or duality, traps the individual in the eternal cycle of worldly existence, or Samsara, where death follows birth and rebirth follows death.
