What, according to the teachings in the Satcharitra, is the root cause of being trapped in the cycle of birth and death?

Chapter 37 of the Shri Sai Satcharitra identifies the root cause of being trapped in the cycle of worldly existence (Samsara) as the ignorance that creates a sense of separation from the divine. The text explains that a person who holds the belief, "Parabrahman is different from me; I am not that," is deluded by this knowledge of difference. This mistaken perception of duality is what subjects the soul to the eternal cycle where "Death follows birth, and rebirth follows death." As Chapter 37 implies, liberation from this cycle is only possible by overcoming this ignorance and realizing the oneness of the Self with the ultimate reality, Brahman.
