What does Chapter 37 identify as the root cause of being trapped in the cycle of birth and death, and how does it contrast this with the path to liberation?

Chapter 37 identifies the root cause of being trapped in Samsara—the eternal cycle of birth and death—as a fundamental ignorance that creates a sense of separation from the divine. The text states that a person who holds the belief, "Parabrahman is different from me; I am not that, I am something else," is always subject to death and rebirth. This perceived difference or duality is the core delusion. The path to liberation, therefore, involves dissolving this delusion. The chapter suggests that "the science of the oneness of Brahman and the Self is the means" to freedom. On a practical level, it praises the earth-world as a unique place where liberation is attainable. It states that even with a fleeting life, one "who offers every action performed in a moment to God attains the place of fearlessness," thus transcending the cycle.
