What is the author's plea to the listeners in Chapter 15, and how is it justified using the metaphor of an ocean?

The author in Chapter 15 makes a heartfelt plea to the listeners, asking them for their grace, attention, and forgiveness for any shortcomings. This plea is justified through the powerful metaphor of an ocean. The text explains that just as a vast ocean accepts all rivers without judgment—whether it's the pure water of the Ganges or a muddy village stream—the author hopes the gracious listeners will accept his humble story. This comparison, as laid out in Chapter 15, emphasizes the author's humility and his deep desire to immerse his narrative within the receptive hearts of his audience, hoping they will not 'desert the lowly.'
