Chapter 37 discusses the cycle of birth and death. What is the root cause of this cycle, and how does it contrast with the true heavenly state?

According to Chapter 37, the primary cause of being trapped in the eternal cycle of worldly existence (Samsara), where death follows birth and rebirth follows death, is the delusion of separateness. The text states that one who holds the belief that 'Parabrahman is different from me; I am not that' is always subject to death. This state of ignorant delusion and perceived duality is directly contrasted with the true heavenly state, which is described as the realization of the Virat Self-form, free from mental grief. This divine state, as explained in the chapter, is one of non-duality and fearlessness, where the same divine principle is seen pervading all of creation.
