In the spiritual lore of India there is a story that the Lord whispered only one word in our ears when he sent us into the world: "Give." Give freely of your time, your talent, your resources; give without asking for anything in return. This is the secret of living in joy and security. The moment you expect reward or recognition, you are making a contract.

Eknath Easwaran, The Bhagavad Gita for Daily Living, Volume 2
