What does Chapter 37 identify as the primary cause for an individual remaining trapped in the cycle of worldly existence (Samsara)?

According to Chapter 37, the root cause of being trapped in the eternal cycle of birth and death, known as Samsara, is a deluded sense of separation from the divine. The text explains that a soul deluded by ignorance develops the knowledge of difference, thinking, 'Parabrahman is different from me; I am not that.' This perception of duality and separateness is what subjects the individual to the continuous cycle where death follows birth and rebirth follows death. The chapter emphasizes that the same divine principle pervades everything, and realizing this oneness is key to liberation.
