3 Sounds of Light

Three Rays of Sound
According to the druidic teachings : "Men Heim watched the light, saw the Three Columns that were light and sound at the same time, and understood that Word and Light produced Life". So the Uncreated gives rise to the three fundamental principles from which all the Forces of Creation stem.
The Druids render these Three Sounds of Light (or conversely these Three Rays of Sound) into the three letters O.I.V. and they wear a triban on their bandeau.
