How does the author of Chapter 15 use the metaphor of an ocean and rivers to address the audience?

In Chapter 15, the author employs the metaphor of an ocean and rivers to establish a relationship of humility and respect with the listeners. The author compares the audience to a great ocean, which is vast and accommodating, and himself to a river seeking to merge into it. The text notes that an ocean accepts all waters, whether it's the pure water of the Ganges or a muddy village stream, without commotion. By using this analogy, the author is humbly requesting the listeners to graciously accept his stories, regardless of perceived imperfections, and to allow him to immerse his narrative in their collective attention and grace.
