He then walks to the tree temple with torch in hand when we see two familiarly pointy ears. Luke looks behind him. "Master Yoda." "Young Skywalker." "I'm going to end this. The Jedi. The tree. The texts. I'm burning it all down." Luke approaches the temple but does nothing. Yoda however uses the force to fling the torch out of his hand, setting the ancient tree ablaze, then laughs his ass off about it. Luke is set back by an explosion and gazes in horror.
"I-it's over… The Jedi Order… It's finished…" "Only as you know it." "But Master! The sacred Jedi texts!" "Ah yes. Wisdom, they held. But page turners, they were not. Nor define the Jedi Order, they did. Besides, that library contained that the girl Rey already possesses, it does not. Young Skywalker… Still looking to the horizon. Never here! Now! The need in front of your nose!" "I was weak… Unwise…"
"Lost Ben Solo, and young Jacen, you did. Lose Rey, we must not." "But I can't be what she needs me to be." "Heeded my words, have you not? Pass on what you have learned. Strength. Mastery. But weakness, folly, failure also. Yes, failure most of all. Think the first Jedi in history to fail, are you?" "Well no but-" "Yes. Yes. Failed many times, the Jedi have in the past. But never have we let failure define who we are. Nor stop us from bettering us those who lived, did we let it. For the greatest teacher, failure is."
Yoda sits next to Luke to watch the tree burn. "What of hubris…? It almost destroyed the Jedi twice… Both caused by Skywalkers…" "Not even the Sith, able to destroy the Jedi were they. Destruction by overconfidence? Maybe so. But worst of all, self doubt is. Never leads to betterment, it does." The two just sit there watching the tree burn.
