Based on Chapter 37, what causes the cycle of death and rebirth, and what are the 'nooses of death' that bind a person?

Chapter 37 explains that the endless cycle of worldly existence, or Samsara, where death follows birth and rebirth follows death, is perpetuated by a specific kind of ignorance. This cycle entraps the person who holds a sense of difference, believing, "Parabrahman is different from me; I am not that." This feeling of separation is the root cause. The text also identifies what it calls the 'nooses of death,' which are Adharma (unrighteousness), ignorance, anger, and hatred. It is only by entirely crossing these negative qualities that one can enter the true heavenly state, which is a state of being free from mental grief.
