Danh ngôn của Pedro Calderon de la Barca (Sứ mệnh: 6)

When love is not madness, it is not love.
What is life? A madness. What is life? An illusion, a shadow, a story. And the greatest good is little enough; for all life is a dream, and dreams themselves are only dreams.
One may know how to gain a victory, and know not how to use it.
For all life is a dream, and dreams themselves are only dreams.
What law, what reason can deny that gift so sweet, so natural that God has given a stream, a fish, a beast, a bird?
Green is the prime color of the world, and that from which its loveliness arises.
These flowers, which were splendid and sprightly, waking in the dawn of the morning, in the evening will be a pitiful frivolity, sleeping in the cold night's arms.
For even in dreams a good deed is not lost.
