According to Chapter 37, what is the primary reason an individual remains trapped in the cycle of birth and death, and what is the role of Parabrahman in this context?

The root cause for being perpetually caught in the cycle of worldly existence (Samsara) is identified in Chapter 37 as a fundamental ignorance that creates a sense of duality. This ignorance is the belief that "Parabrahman is different from me; I am not that." The text clarifies that the same divine principle, Parabrahman, pervades everything, from the creator down to a blade of grass. However, a soul deluded by this ignorance fails to recognize this universal unity and perceives itself as a separate entity. It is this specific "knowledge of difference" that subjects the soul to the unending cycle of birth, death, and rebirth.
