We cannot live without air. It is everywhere surrounding us. Many things are carried by the air. The seeds with wings are scattered in the air. Leaves are blown off the trees by air.
Air travel is used to carry passengers, much needed supplies and the mail.
Transmission of radio, television and micro waves are carried in the air. Air represents communication and new ideas. Without air we could not breathe. Also, air is something you know is there but cannot see. The Third candle we'll light represents the South and the Element Fire.
