Famous quotes containing the word heart:
“One enemy, of many, who knows well
Your heart is luminous
In the watched dark, quivering through locks and caves,
Will pull the thunderbolts
To shut the sun, plunge, mount your darkened keys....”

“A heart that overflows may seek out merrymaking and boisterous festivities to quietly rejoice, unnoticed amidst the reveling crowds.”
—Franz Grillparzer (17911872)
“Nothing is so insufferable to man as to be completely at rest, without passions, without business, without diversion, without study. He then feels his nothingness, his forlornness, his insufficiency, his dependence, his weakness, his emptiness. There will immediately rise from the depth of his heart weariness, gloom, sadness, fretfulness, vexation, despair.”
—Blaise Pascal (16231662)
