Star Wars: The Clone Wars, Season 1

Yoda:
Come. Sit. Your helmets, remove them. Your faces I wish to see.

(Thire, Rys and Jek remove their helmets)

Lieutenant Thire:
There's not much to look at here, sir. We all share the same face.

Yoda:
Deceive you, eyes can. In the force, very different each one of you are. Rys, always focused on the enemy, are you. For inspiration, look to yourself, and those beside you. Jek, concerned about weapons you are. Weapons do not win battles. Your mind, powerful it is. Out-think the droids, you can. Thire, rush not into fights, long is the war, only by surviving it, will you prevail. Clones you may be, but the force resides in all life forms. Use it you can, to quiet your mind.
