What is the nature of death and the cycle of rebirth according to the teachings in Chapter 37?

Chapter 37 explains that what we call 'death' is simply the transition of a being from its manifest state back into the unmanifest. The true 'nooses of death' are not a physical end but spiritual failings such as unrighteousness (adharma), ignorance, anger, and hatred. The text clarifies that one who believes they are separate from the ultimate reality, the Parabrahman, becomes subject to the eternal cycle of worldly existence, or Samsara. This cycle of death followed by birth, and rebirth followed by death, continues for those who maintain a sense of difference from the divine. To escape this cycle, one must overcome these spiritual failings and realize the oneness of the Self with Brahman.
