Could you explain the relationship between duality and fear as described in the text?

The text in Chapter 37 establishes a direct causal link between duality and fear. It clearly states, 'Where there is an obsession with duality, there fear enters.' This means that fear is a direct consequence of perceiving the world in terms of differences and separation—seeing oneself as distinct from others and from God. This perception of 'manifoldness' is identified as a product of ignorance (Avidya). To find freedom from fear, the text advises one to 'serve the non-distinguished state where there is not even a trace of fear.' The solution, therefore, is to cultivate a non-dual intellect through the Guru's grace, which dissolves the illusion of separation and establishes the devotee in the fearless state of oneness.
