One of the greatest quotes about love from Shakespeare comes from "Romeo and Juliet," when Juliet says to Romeo: "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." Here, Juliet is explaining that her love for Romeo is so deep it has no limit, and that offering him her love only generates more love within her.
Another quote about love comes from Shakespeare's "The Tempest," when Ferdinand says to Miranda, "Hear my soul speak / The very instant that I saw you did / My heart fly to your service." In other words, Ferdinand wants Miranda to know that, even though he is a prince, he will perform the tasks of a servant in order to prove his loyalty and win her heart.
Performing these tasks, however, is not merely a way of showing off for her. Ferdinand explains that his desire to work as a slave for Miranda stems from his very soul and is born of his intense love for her. Ferdinand will compromise his own pride and dignity for Miranda's sake because he is willing to do whatever it takes to be with her.
