Two thoughts, actually.
"Can miles really separate us from friends? If you want to be with someone you love, aren't you already there?"
"Don't be dismayed by good-byes. A farewell is necessary before you can meet again. And meeting again, after moments or lifetimes, is certain for those who are friends."
- Richard Bach

OK, one more:
“Don’t believe what your eyes are telling you. All they show is limitation. Look with your understanding. Find out what you already know and you will see the way to fly."
