How does the concept of duality relate to the fear of death, and what is the prescribed solution?

The text directly links the fear of death to the concept of duality. Chapter 37 explains that where there is an obsession with duality, or a perception of difference, fear will inevitably enter. This view of difference is what keeps one trapped in the sufferings of birth and death, with destruction and creation constantly following them. The solution prescribed is to embrace the non-dual state. This is achieved by acquiring knowledge (Vidya) from the Guru and scriptures to remove ignorance (Avidya), which is the root of the perception of manifoldness. To become fearless from death, one must hold firmly to the Guru's feet, as He will grant the non-dual intellect. The text advises serving the 'non-distinguished state where there is not even a trace of fear.'
