There is an ancient tradition that when Divine Revelation comes into the world, only one part is given as prophetic writings.The words are only a part of the message.The other part is placed within nature, the wisdoms inherent in the Creation.Only when we understand those hidden wisdoms will we be able to read between the prophetic lines and fully understand the message.
Sometimes the bird turns away. Sometimes it does not open its mouth to sing. Sometimes it is afraid of the dark. But when it forgets it is afraid and opens its mouth to sing, it fills the world with light.
