Chapter 37 mentions the cycle of Samsara. From a non-dualistic perspective, what is the root cause of being trapped in this cycle of birth and death, and what is the ultimate reality we should realize?

According to the teachings in Chapter 37, the eternal cycle of worldly existence, or Samsara, is perpetuated by a fundamental delusion. The text explains that the same divine principle, Parabrahman, pervades all things, yet it can appear different to a soul deluded by ignorance. The root cause of being subject to death and rebirth is the 'knowledge of difference'—the belief that 'Parabrahman is different from me; I am not that.' This sense of separation is what keeps the soul bound. The ultimate reality to realize is the oneness of Brahman and the Self, which is the means to liberation and the way to cross the 'nooses of death' like ignorance, anger, and hatred.
