Can you explain the non-dualistic philosophy regarding the individual soul and Parabrahman as described in the source, and its connection to the cycle of rebirth?

Chapter 37 delves into the advanced non-dualistic principle that the individual soul and Parabrahman are one. The text explains that the root of suffering and rebirth is the ignorance that creates a sense of separation. As Chapter 37 states, the person who believes, "Parabrahman is different from me; I am not that, I am something else," possesses a "knowledge of difference" and is therefore "always subject to death." This perceived duality is what perpetuates the cycle of worldly existence, or Samsara. The text makes this link explicit: "Death follows birth, and rebirth follows death; this cycle of worldly existence (Samsara) turns eternally behind him." Thus, liberation is found in transcending this illusion and realizing the science of the oneness of Brahman and the Self.
