According to the philosophy in Chapter 37, what are the real causes of death, and how can one overcome them?

Chapter 37 redefines our understanding of mortality. It states that what we call 'death' is merely the manifest form returning to the unmanifest state. The true obstacles, referred to as the 'nooses of death', are identified as adharma (unrighteousness), ignorance, anger, and hatred. To truly overcome death and the cycle of rebirth, one must cross beyond these negative qualities entirely. The text further explains that the belief that 'Parabrahman is different from me' is a delusion born of ignorance that keeps one subject to the eternal cycle of worldly existence. Therefore, overcoming death involves transcending these internal 'nooses' and realizing the non-dual nature of the Self and Brahman, which leads to a fearless state.
