Famous quotes containing the word heart:
“My heart is like a singing bird
Whose nest is in a watered shoot;
My heart is like an apple-tree
Whose boughs are bent with thickset fruit;
My heart is like a rainbow shell
That paddles in a halcyon sea;”

As though on my beloved,
And my blood be cold the while
And my heart unmoved?
Why should he think me cruel
Or that he is betrayed?”

King Richard. Ay, hand from hand, my love, and heart from heart.”
