How does Chapter 37 explain the concepts of death and the cycle of rebirth (Samsara)?

Chapter 37 defines death as the process where a manifested form returns to the unmanifest state. However, it emphasizes that the true 'nooses of death' are internal states like unrighteousness (adharma), ignorance, anger, and hatred. The text explains that the cycle of worldly existence, or Samsara, where birth is followed by death and death by rebirth, is perpetuated by a specific delusion. This delusion is the knowledge of difference—the belief that 'Parabrahman is different from me.' One who holds this dualistic view, seeing themselves as separate from the Supreme Reality, remains eternally subject to this cycle.
