We all go to the sea with our little containers: a cup, a bucket, a barrel. We gather water. “Hey, did you get some seawater?” “Yes.” How is it?” “Oh, it’s in the shape of a mug.” “How could that be? See, I got some and it’s in the shape of a bucket!” Another, “It’s only in the shape of a test tube.” They're talking about the containers, not about the contained.They all got seawater. Those who see the seawater and not just the container are called the seers.
