What is the significance of the author comparing listeners to an ocean in Chapter 15?

In Chapter 15, the author compares the listeners to an ocean to express deep humility and to request their grace and acceptance. This metaphor highlights the ocean's immense capacity to accept everything without discrimination, whether it's the pure water of the Ganges or a muddy village stream. As mentioned in the text of Chapter 15, the author wishes to 'immerse myself in you,' trusting that the listeners, like the ocean, will not turn back the stories being offered. This comparison serves to create a respectful and receptive atmosphere, emphasizing that the listeners' own interest in the stories of saints will be fulfilled through their gracious attention.
