What does this text say about the cycle of birth and death, and what causes a person to be trapped in it?

The scripture explains the perpetual cycle of worldly existence, known as Samsara, in a straightforward manner. As detailed in Chapter 37, it is an eternal cycle where 'death follows birth, and rebirth follows death.' The primary reason a soul remains trapped in this relentless cycle is the presence of a sense of difference or separation from the ultimate reality. The text states that one who believes, 'Parabrahman is different from me; I am not that,' is always subject to death and the subsequent rebirth. This knowledge of difference, this delusion of being separate, is what keeps the wheel of Samsara turning eternally.
