Master Yoda

Fear is the path to the dark side. Fear leads to anger. Anger leads to hate. Hate leads to suffering.

— All right, I'll give it a try.
— No. Try not. Do... or do not. There is no try.

Truly wonderful the mind of a child is.

Use your feelengs you must.

Yes! A Jedi's strength flows from the Force. But beware of the dark side. Anger, fear, aggression... The dark side of the Force are they, easily they flow,
quick to join you in a fight. If once you start down the dark path, forever will it dominate your destiny.

The fear of loss is a path to the dark side.

When 900 years old you reach, look as good you will not.

Luke, we are what they grow beyond. That is the true burden of all masters.

Twilight is upon me, and soon night must fall. That is the way of things... the way of the Force.

Size matters not. Look at me. Judge me by my size, do you? Hmm? Hmph! And well you should not, for my ally is the Force. And a powerful ally it is.

Twisted by the dark side young Skywalker has become. The boy you trained, gone he is. Consumed by Darth Vader.

Death is a natural part of life. Rejoice for those around you who transform into the Force. Mourn them, do not. Miss them, do not. Attachment leads to jealousy. The shadow of greed that is.

The greatest teacher, failure is.

If so powerful you are... why leave?

— I'm looking for a great warrior.
— Ah! A great warrior. Ha-ha-ha! Wars not make one great.
