It’s not from the OT, but Qui-Gon says, “Your focus determines your reality.” I often use that phrase to reset myself when I just need to movie on from something.
I have been focusing on Penelope Cruz for a long time now, but she not yet become a reality in my life. Sad times. A memorable phrase regardless!
“The Force is what gives a Jedi his power. It’s an energy field created by all living things. It surrounds us and penetrates us. It binds the galaxy together.”
and
"For my ally is the Force. And a powerful ally it is. Life creates it, makes it grow. Its energy surrounds us, binds us. Luminous beings are we, not this crude matter. You must feel the Force flow around you. Here, between you, me, the tree, the rock, everywhere. Yes, even between the land and the ship.”
Classic and timeless, my friend.
