Describe the Ocean of the Stream of stories.

From the text:

This is the Ocean of the Streams of Story.
Every tale that has been told is here
And every tale that has yet to be invented
And if you’re very careful
[Very careful or very highly skilled]
You can dip a cup into the ocean
And fill it with a single story –
A single pure stream of story
Like so.
Go on now. Knock it back.
Guaranteed to make you feel
A-number-one.
