I have given no definition of love. This is impossible, because there is no higher principle by which it could be defined. It is life itself in its actual unity. The forms and structures in which love embodies itself are the forms and structures in which love overcomes its self-destructive forces.
Paul TillichWe can speak without voice to the trees and the clouds and the waves of the sea. Without words they respond through the rustling of leaves and the moving of clouds and the murmuring of the sea.
