Why does the author of Chapter 15 compare the listeners to an ocean?

In Chapter 15, the author uses the analogy of an ocean to humbly request the grace and attention of the listeners. The text explains that just as an ocean accepts all rivers limitlessly—whether it's the pure water of the Ganges or a muddy village stream—and gives them a place, the author hopes the listeners will accept his words. He states, "Even when the clouds pour thousands of showers, it gives them all a place." By drawing this comparison mentioned in Chapter 15, the author expresses his desire to immerse himself in the good listeners and asks them not to rebuke him, emphasizing that it is not good to desert the lowly. It is a plea for open-hearted reception of the sacred stories.
