All of the Runes have an image, or symbol, that sets the train of recollection, ideology, and meaning in motion. This image isn't the 'meaning' of the rune, it is the picture that sparks off of the meaning and gives it form and reality.

The prompt-symbol for Cennaz is the opening in a lantern. Facts, research, and reflection all combine together to form understanding. Understanding then becomes a light to help us on our path. The message of Cennaz is that the lantern-light only helps us when it is actually pointing in the direction that we are going. “Use your understanding!” Cennaz says.
