How does the concept of duality contribute to the fear of death, and what is the solution presented?

According to the teachings in Chapter 37, the perception of duality, or manifoldness, is the very entry point for fear. The text explicitly states that where there is an obsession with duality, fear enters. This perception of difference is rooted in ignorance (Avidya). The constant cycle of birth, death, destruction, and creation follows anyone who holds even a slight view of difference. The solution is to acquire knowledge and embrace the science of oneness, where there is no trace of fear. By serving the non-distinguished, non-dual state through the guidance of a Guru, one can overcome the fear of death.
