“Working with keys is always meaningful. Locking and opening is, in a sense, man's very purpose on this earth.”

“At first glance, the key and the lock it fits may seem very different," Sazed said. "Different in shape, different in function, different in design. The man who looks at them without knowledge of their true nature might think them opposites, for one is meant to open, and the other to keep closed. Yet, upon closer examination he might see that without one, the other becomes useless. The wise man then sees that both lock and key were created for the same purpose.”

“All of us are like locks. No matter how strong the bolt, there’s always a key out there that opens it.”

“Jealousy is the lock that closes your heart, understanding is the key that opens it.”

“Never try to lock the virtue’s door with the key of viceIt may lock forever; never to be opened again”

“If getting is the key to your happiness your key will open few doors. If giving is the key to your happiness you will find few doors locked.”
