How does the author of the Satcharitra address the audience at the beginning of Chapter 15, and what is the significance of the ocean metaphor?

At the start of Chapter 15, the author makes a humble address to the listeners, asking them to prepare their minds and give their attention to the story. The author uses the metaphor of an ocean to describe the audience, noting that an ocean accepts all rivers without turning any back, whether it is the pure Ganges or a muddy stream. As detailed in Chapter 15, the author expresses a desire to 'immerse' themselves in the listeners, just as rivers merge with the sea. This metaphor signifies the author's humility and the hope that the audience will graciously accept the stories, regardless of their perceived quality, leading to their own spiritual fulfillment.
