Brim: The edge of water, especially an edge created by water tension and lying above the surface of the water. Unbroken, it holds the water in place. If touched, the water flows out of it. This flowing is called brimming. It transfers the edge of water into water itself. The flow continues to be created out of that boundary. It is this energy which fills a well. In this sense, a well is a spell made of earth, which creates a brimming space that draws water to it out of the soil and liquifies it.
