Can you elaborate on the ocean metaphor used in Chapter 15 to describe the audience?

In Chapter 15, the author humbly uses the metaphor of an ocean to characterize the listeners, emphasizing their capacity for grace and acceptance. The text explains that just as the boundless ocean does not turn back any river and provides a place for thousands of showers, the listeners are requested to give the author's stories a place in their hearts. Chapter 15 further illustrates this by noting that both the pure water of the Ganges and the muddy stream of a village find a place in the ocean's belly without any commotion. This comparison serves as a plea for the listeners to accept the author's humble offering with the same unconditional vastness, which will lead to their own fulfillment.
