Feathers are of the Air element.
Dreams, aspirations, and wishes all ride in the breath of the wind. Wind moves around us and through us. We are not passive lumps in the swirls and eddies of wind currents, but rather participants, as our thoughts and intents engage with this element.
The feather is a good symbol to remind us that what we think and say, travels on the wind affecting everyone around us.
The feather is a good symbol to remind us that our dreams and aspirations can reach anywhere, even to places we can not yet see.
