But Yoda is also a great philosophical companion. I learned from him...
Mindfulness: "This one a long time have I watched. All his life as he looked away... to the future, to the horizon. Never his mind on where he was. What he was doing!"
Make decisions from a place of calm: Luke "But how am I to know the good side from the bad? Yoda "You will know. When you are calm, at peace. Passive." I just came across a study that studied decision making among non-meditators, and regularly meditating monks. They found different parts of the brain lit up. The monks made decisions based on rationality, and not on emotion (such as whether they felt they were being treated fairly.)
What you think you create: (At the tree) Yoda "In you must go." Luke "What's in there?" Yoda "Only what you take with you."
(After Yoda raises the ship.) Luke "I don't believe it!" Yoda "That is why you fail."
Have faith in your abilities: "Always with you it cannot be done. ...Do or do not. There is no try."
We're all one: "You must feel the Force around you. Here, between you, me, the tree, the rock, everywhere! Yes, even between the land and the ship." Jill Bolte-Taylor learned that our right brains see the world this way.
Don't be superficial: "Judge me by my size do you? And well you should not. For my ally is the Force, and a powerful ally it is." This is why it saddens me when people complain that the final battle in Return of the Jedi should have been with wookies and not ewoks. As if the Empire would build a base on a wookie planet! The whole point is they underestimated the wee local natives.
And finally: We're bundles of energy, just like all the other life around us!
Luminous beings are we. Not this crude matter!
