When we westerners pray we join our hands, close our eyes, kneel, hunch up and put our hands over our faces to close up our bodies. Our God is inside us, his universe inside our heads. When Orthodox Christians pray they keep their eyes open. They hold their heads up and open up their senses to the universe. Their God is outside in a real world.
