Words are loudly spoken and sung by human voices, but they break also the silence, nevertheless preserving the silence in the little pauses between the words. Words suddenly come up in the mind of the speaker, and words, remain hidden in the bosom of the silent thinker. The political slogan is shouting, asking for attention and applause, my heart is pondering the words of a psalm. The word is heard and done, but also: the word is heard and forgotten. Words reveal our motives, but at the same time they conceal our inner world.
