How does David Lynch use imagery in Catching the Big Fish?

Imagery:

"All religions flow ultimately to one ocean."
Pg. 101

"If you want to catch little fish, you can stay in the shallow water. But if you want to catch the big fish, you’ve got to go deeper. Down deep, the fish are more powerful and more pure.They’re huge and abstract. And they’re very beautiful.”

“The beautiful thing is that when you catch one fish that you love, even if it’s a little fish—a fragment of an idea—that fish will draw in other fish, and they’ll hook onto it. Then you’re on your way. Soon there are more and more and more fragments, and the whole thing emerges. But it starts with desire.”
