How does the author of the Satcharitra address the listeners in Chapter 15, and what is the significance of the ocean metaphor?

In Chapter 15, the author addresses the listeners with profound humility, asking them to show grace and prepare their minds for the story. He employs the powerful metaphor of rivers flowing into the ocean to define this relationship. He compares his storytelling effort to a river, and the audience to the vast ocean that accepts all waters without discrimination, whether it's the 'pure water of the Ganges or the muddy stream of a village.' By using this imagery, the author asks the listeners to accept his words openly, without judgment. He expresses his wish to 'immerse' himself in them and pleads with them not to rebuke him, stating 'it is not good to desert the lowly.' This metaphor, as detailed in Chapter 15, sets a tone of humble offering and respectful reception.
