" The sound of water is deep, its form is serpent-like, its color green, and it is best heard in the roaring of the sea.

The sound of fire is high pitched, its form is curled, and its color is red. It is heard in the falling of the thunderbolt and in a volcanic eruption.

The sound of air is wavering, its form zigzag, and its color blue. Its voice is heard in storms, when the wind blows, and in the whisper of the morning breeze. "
