Nature is a system of life energy in constant flow, peaceful one moment and turbulent the next. All living things draw their life from it, and depend upon its balance for their existence. Druids are the protectors of this balance, who harness the energies it contains and try to live their lives according to its laws and principles. In this way, they become intimate members of the natural system, embodying the very force that they seek to protect. The druid is not merely a spellcaster who draws on nature to do cool stuff -- he is nature, in himself, completely one with it in every way. The world is his body, and he is an inseparable part of the whole.
It can be rather hard for those of us living in the concrete jungles of modern city life to get a feeling for what nature really is, or what it feels like to be a part of it. Perhaps if you have ever ventured off the paved highway into the distant reaches of the world, you will know the feeling of connection to the greatness of the natural world in which the human race evolved, long, long ago in a state of mind far, far away from billboards and electronic devices, pop culture and prime-time TV programming. It may no longer be possible for human beings to simply return to its ancient state, nor would that necessarily be a good thing. Today, people look out at the world outside the closed-off bubble of material civilization and wonder their new relationship with the ancient balance of nature could be.
To play a druid in WoW as a class in a game is one thing, but to try and get inside the druid worldview and understand what they might be thinking is something else. To start, it would help to look inside ourselves and see what sort of connection to nature exists there. Is there a balance? What would balance look like? How would it feel to be in complete harmony with the natural world? What would it be like to channel all the power of nature through your body or indeed feel the world itself as an extension of your body?
