The Northern Temple is often the surrounding sand, which is believed to come from the Apocalypse of the temple like a pure religious universe. By having a unique pagoda instead of God, in comparison, is Mount Meru, which, as the center of the temple, and a group of buildings in both the Cathedral or the Church surrounding empty space between the sand is to be like the sea sithandon surrounding Mount Meru. When sunlight reflects these sand and shadow, it will change to resemble the waves in the sea, really.
