What does Chapter 37 teach about the cause of the cycle of birth and death, also known as Samsara?

According to the philosophical insights in Chapter 37, the primary cause of being trapped in the eternal cycle of worldly existence (Samsara) is ignorance, specifically the deluded notion of being separate from the ultimate reality. The text explains that a person who thinks, "Parabrahman is different from me; I am not that, I am something else," possesses a knowledge of difference that subjects them to death. This belief perpetuates the cycle where, as the chapter states, "Death follows birth, and rebirth follows death." The text also identifies adharma, ignorance, anger, and hatred as the "nooses of death," which bind the soul to this cycle. Overcoming this ignorance and realizing one's unity with the divine principle is the path to liberation from Samsara.
