Using the metaphor from the text, how is the grace of a Guru like an ocean?

Chapter 15 uses the metaphor of an ocean to describe the unconditional acceptance of a Guru and the receptive nature of a spiritual gathering. The text states that just as an ocean accepts all rivers, from the 'pure water of the Ganges' to the 'muddy stream of a village,' without commotion, so too should listeners and the Guru be open. The narrator wishes to 'immerse' himself in the listeners, highlighting the boundless capacity of the Guru's grace to embrace all devotees, regardless of their state. This analogy emphasizes humility and the immense, non-discriminating love that is a hallmark of a true Guru.
