Quote from : City of Stairs Book

A people believe in a god' - she completes the circle -' and the god tells them what to believe. It's a cycle, like water flowing into the ocean, then up to the skies, and into rain, which falls and flows into the ocean. But it is different in that ideas have weight. They have momentum. Once an idea starts, it spreads and grows and gets heavier and heavier until it can't be resisted, even by the Divine.
