William Shakespeare
"Love is a smoke raised with the fume of sighs; Being purged, a fire sparkling in lovers' eyes; Being vexed, a sea nourished with loving tears. What is it else? A madness most discreet, A choking gall, and a preserving sweet."
"Love is not love Which alters when it alteration finds, Or bends with the remover to remove: O no! it is an ever-fixed mark That looks on tempests and is never shaken."
"My bounty is as boundless as the sea, My love as deep; the more I give to thee, The more I have, for both are infinite."
"But love, first learned in a lady's eyes, Lives not alone immured in the brain, But with the motion of all elements, Courses as swift as thought in every power, And gives to every power a double power, Above their functions and their offices."
"I love you more than words can wield the matter, Dearer than eye-sight, space, and liberty, Beyond what can be valued, rich or rare, No less than life, with grace, health, beauty, honour."
