How does the author of Chapter 15 use the analogy of an ocean to address the listeners?

In Chapter 15, the author humbly addresses the audience by comparing them to a vast ocean. The text points out that an ocean does not turn back any rivers, accepting both the pure water of the Ganges and the muddy stream of a village without commotion. Similarly, it accepts thousands of showers from the clouds. The author uses this analogy to express a desire to immerse themselves and their story into the listeners, asking not to be rebuked for being 'lowly.' As explained in Chapter 15, this metaphor conveys a deep sense of humility and a plea for graceful acceptance from the audience.
