What are the 'nooses of death' and how are birth and death defined in the spiritual context of Chapter 37?

According to the teachings in Chapter 37, 'death' is defined as the state when that which came into form from the unmanifest enters the unmanifest again. This chapter identifies the true 'nooses of death' not as a physical end, but as Adharma (unrighteousness), ignorance, anger, and hatred. Furthermore, the text explains that the belief in separateness, thinking 'Parabrahman is different from me,' is what subjects a person to the eternal cycle of worldly existence (Samsara), where death follows birth and rebirth follows death.
