How does the author of the Shri Sai Satcharitra address the audience in the introduction of Chapter 15, and what is the significance of the ocean metaphor?

In the opening verses of Chapter 15, the author addresses the audience with profound humility, asking them to show grace and give their attention to the story. The author uses a powerful metaphor, comparing the listeners to a vast ocean and himself to a river. As described in Chapter 15, the ocean gives a place to all rivers, whether it's the pure Ganges or a muddy village stream. This signifies the author's hope that the good listeners will accept his humble offering of the story without judgment. By wishing to 'immerse' himself in them, the author establishes a relationship of reverence and dependence on the audience's receptive hearts for the story to achieve its purpose.
