How does the text explain the cause of the cycle of rebirth and the path to overcoming it?

The text from Chapter 37 posits that the root cause of the cycle of worldly existence (Samsara), where rebirth follows death, is a deluded sense of separation from the divine. It states that one who believes, "Parabrahman is different from me; I am not that," is always subject to death and rebirth. This knowledge of difference perpetuates the cycle. The path to liberation is implied to be 'the science of the oneness of Brahman and the Self.' This path involves transcending ignorance and realizing that the same divine principle pervades everything, from the creator down to a blade of grass.
