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.
The human heart has been so made by Love that, like a flint, it contains a hidden fire which is evolved by music and harmony, and renders us beside ourselves with ecstasy. These harmonics are echoes of that higher world of reality which we call the world of spirits...they fan into a flame whatever love is already dormant in the heart.
