What is the root cause of being trapped in the cycle of birth and death (Samsara) according to Chapter 37, and what is the solution?

According to the insights in Chapter 37, the fundamental cause of being trapped in the eternal cycle of birth and death, known as Samsara, is the delusion of separateness. This ignorance is characterized by the thought, 'Parabrahman is different from me; I am not that, I am something else.' The text states that anyone who holds such a belief in difference is always subject to death and rebirth. The solution, therefore, lies in realizing the science of the oneness of Brahman and the Self. This is the means to overcome the delusion. The text explains that the same divine principle pervades everything. By overcoming ignorance and the 'nooses of death' like anger and hatred, and by realizing this non-dual reality, one can cross the cycle of Samsara and attain a fearless, divine state.
