If we put Diwali within a spiritual context, we are in fact those living lights, the dipaks. The clay represents the body and the light, the wick, is the soul. The oil represents the experiences of life itself. Once we apply the oil of knowledge (wisdom) and strike the connection with the Supreme, we are illuminated, enlightened, and begin to share that light with others. When enough of us come together that critical mass will light up the world. All darkness of the world will disappear.
