My (Current) Definition of Druidry
(A personal disclaimer. I do NOT claim to speak on behalf of anyone or any group and this includes the ancient Druids. No one knows what they believed in so why in the world would I know? This is strictly my opinion and may or may not relate to your own beliefs)
In my opinion, druidry is the development of one’s Self (and society) through observation of the natural forces of the universe. I sort of follow a Nietzschean-based version of this. Everything is about finding the balance and unity between two opposites, the Apollinian and the Dionysian. The Apollinian you can think of as the order impulses. The impulse of creation and patterns. The Dionysian would be the opposite. It would be that of chaos and destruction. This gyration of the two opposing sides is what society and our individuals Selves do throughout each relative history. What druidry does, is it attempts to find a type of internal balance and unity of these two opposites.
