It deals with the fluidity of actions. for is symbolised by the ebb and flow of the emotions that are represented by the body of water. The depth of the water, the depth of the emotions. The speed of flow ... the movement of those emotions. Unlike the obstacles and barriers of Hagall and Is, which both represent the fluidity of water inhibited, the Rune Laguz deals with the subconscious and its effect on the characteristics of the emotions in a situation.
"Water is the symbol of unconscious and invisible Life forces. All of life is dependent on water, and therefore Laguz represents the universal ocean, the supreme unity of all life: past, present and future. The dream state and the Jungian “shadow” element both linger beneath its surface, and the human unconscious is revealed when explored and exposed to the conscious mind. We ‘take the plunge’. To the runic initiate the unconscious forces are controlled for good use through mastery of runic skills. Still, the initiate understands the potency of the unconscious sea to break loose from its control and is ever watchful." (Runic Secrets)
