How does Chapter 37 define death, and what causes the cycle of rebirth?

Chapter 37 offers a philosophical definition of death, distinct from the mere cessation of the physical body. It describes death as the process when something that has come into form from the unmanifest returns to the unmanifest state. The true 'nooses of death' are identified not as physical ailments but as adharma (unrighteousness), ignorance, anger, and hatred. The text further explains that the cycle of worldly existence, or Samsara, is perpetuated by the deluded knowledge of difference—the belief that 'Parabrahman is different from me.' This sense of separation subjects a soul to the eternal cycle of death and rebirth.
