Stories from around the world tell how even the messy things that deities produce are valuable and important. In Shinto myth the god Izanagi has two deities come out of his eyes and another from his nose. The ancient Egyptian deities Shu and Tefnut were born from Atum’s masturbation.
So it’s no surprise that a goddess’ tears would take the form of amber or gold. In fact, three different stories tell how valuable a weeping goddess could be.
