Here's the passage:
>"My love for Linton is like the foliage in the woods: time will change it, I'm well aware, as winter changes the trees— my love for Heathcliff resembles the eternal rocks beneath— a source of little visible delight, but necessary. Nelly, I am Heathcliff! He's more myself than I am. Whatever our souls are made of, his and mine are the same— and let the great, surging, throbbing waves of the mighty, all-absorbing ocean roll over us, the sea, and the waves, and the earth— shall rise again, in a resurrection, to life, when all is done with. " (Chapter 9)
The line about the "great, surging, throbbing waves of the mighty, all-absorbing ocean roll over us," is often compared to the force of nature and the inevitability of destiny.
While there isn't a direct mention of "Eclipse", it's likely the comparison to the waves of the sea and the idea of a "resurrection" in this passage that you're referring to. The "Eclipse" reference could be drawn from the powerful and destructive nature of the ocean, which is reflected in the intensity of Catherine's feelings for Heathcliff.
