Merlin (chaos) energy
Merlin is a title, not a name.
'The Merlin' (as in "The Merlin of Britain") is therefore the title of a lineage of spiritual masters, mystics, and healers. Merlin, the figure usually understood as the wizard-prophet to King Arthur, belongs to this ancient lineage, as does the Irish figure of Columba and others down the ages, not all of them known by name.
Merlin energy is green, masculine, and concerns itself with the alchemy of transmutation of energy. It was known by the priesthood of Atlantis. It is the sap of the Green Man. It flows from the deity of the woods, known as Cernunnos (KER-noo-nos) by the Gauls, and in Old Irish literature as Uindos, Herne (Hermes), Hu Gadarn, and Hesus (Jesus). He is known as the most ancient and powerful Celtic deity, called the “lord of wild and all things” and "wild god of the forest." In short, his is a propensity for wildness and chaos (re-ordering), an energy that breaks up over-rationality and excessive control. Crazy Wisdom. His sons were said to be Teutates, Esus and Taranis who are sometimes referred to as his doubles.
When challenged, he battles his foes using the plants, roots and trees that he controls. However, Cernunnos is actually a very gentle deity, with a deep and tender care for the forest and all its inhabitants, showing respect even to his enemies by playing music even as they die. He is more a Lover and Protector, than a Fighter.
Cernunnos shows traits and symbols in common with the patron god of healers and magicians known as Hermes or Hermes Psychopomp (conductor of souls), the title given to the Lord of Death (whom the Celts recognized as Cernunnos) in his union with his consort, the Lady of Life.
