What belief keeps a person trapped in the cycle of birth and death, also known as Samsara?

The cycle of worldly existence, or Samsara, where death follows birth and rebirth follows death, is perpetuated by a fundamental ignorance. As explained in Chapter 37, this occurs when a soul, deluded by ignorance, fails to see the divine principle of Brahman in all things. The specific belief that traps an individual is the 'knowledge of difference'—the idea that "Parabrahman is different from me; I am not that, I am something else." Anyone who holds this perception of being separate from the ultimate reality is said to be always subject to death and remains caught in its eternal cycle.
