Be free of Hope and Desire

Inwardly be free of all hopes and desires, but outwardly do what needs to be done. Without hopes in your heart, live as if you were full of hopes. Live with your heart now cool and now warm, just like everyone else. Inwardly give up the idea "I am the doer," yet outwardly engage in all activities. This is how to live in the world, completely free from the least trace of ego.
