In our idea, because we are very teeny, we can see this Pacific Ocean before us—"the greatest." But even in comparison to the universe, it is not even a drop of water. In comparison to the universe there are millions and trillions of Pacific Oceans floating in the sky. So what is this Pacific Ocean in comparison to the universe? Therefore it is not greatest. But to our idea, we are thinking it is the greatest. This is called relative truth. This is scientifically truth, Professor Einstein's theory, relativity.
We think something very great or greatest according to our capacity of understanding. We are very teeny, so we think that this Pacific Ocean, the greatest. The frog philosophy. Everyone is thinking that his understanding is the greatest. He has no idea that how greatest God is. We say "God is great," but we do not know how great He is. This Pacific Ocean is an insignificant drop of water within this universe, this material universe. And this universe is also . . . just like Caitanya Mahāprabhu said that this universe is just like a, a small mustard seed in the bag of a mustard seed. If you take one bag of mustard seeds, you cannot count how many there are. Is it possible? If you take a bag of grains, is it possible to count how many grains are there?
