How does the author address the audience in Chapter 15, and for what purpose?

In Chapter 15, the author addresses the listeners with profound humility, asking them to show grace and forgive any shortcomings in the narration. The text uses the metaphor of an ocean to describe the listeners, noting that just as the ocean accepts all rivers, from the pure Ganges to a muddy stream, the author hopes the listeners will accept their story. The stated purpose of this engagement, as detailed in Chapter 15, is to guide the audience toward spiritual fulfillment. By partaking in this 'nectar-like story' with patience and faith, listeners are promised the attainment of devotion, love, happiness, peace, and ultimately, the destruction of the fear of worldly existence, leading to liberation.
