Can you explain the concept of Samsara, the cycle of birth and death, as described in the Shri Sai Satcharitra?

Chapter 37 explains that the cycle of worldly existence, or Samsara, is driven by a fundamental ignorance. When a person, deluded by this ignorance, believes 'Parabrahman is different from me; I am not that, I am something else,' they create a sense of separation. This knowledge of difference, this duality, subjects the individual to the eternal cycle where death follows birth and rebirth follows death. The text states that this cycle of Samsara turns eternally behind one who holds this mistaken belief of being separate from the ultimate reality, Brahman.
