These epigraphs exemplified what Chris wanted to do. These talk about travel, and the freedom associated with it. Chris wanted to truly be free from material, government control, and anyone telling him what to do. I think these quotes can help establish a balance of freedom and attachment. One should not be so attached to what they have, that when an opportunity comes along, you don't take it. One the other hand, being attached can give you a stable base to live on. Friends and family are a part of being attached. I am sure most people would not give up all contact for the sake of "freedom".
