first of all, i have to to say i LOVE this question. It's right up my ally.
I would say a dandelion or sunflower. A dandelion because of it's changes through it's cycle, and that it has such great purpose. It's beautiful, highly medicinal and while you can think you pulled it's root out to roasted root coffee or just to weed your garden, it's still there. Yet, when it comes to the end of its cycle it is everywhere with a puff of wind. I am rooted to my home town and the places I've been, but I still dance where the wind takes me.
A sunflower because the Spiritualist Church adopted it because it follows the sun through the sky, representing spiritualism turning to the light of truth. I believe strongly in science, and I believe in what we cannot see. I use logic and reason and make educated guesses, but I also still have that child-like love of magic, and hold strongly to that. I want to know the truth, and I do believe the truth involves magic.
thanks for that question. it made me smile :)
