"Size matters not. Look at me. Judge me by my size, do you? Hmm? Hmm. And well you should not. For my ally is the Force, and a powerful ally it is."
Yoda was one of the most renowned and powerful Jedi Masters in galactic history. He was known for his legendary wisdom, mastery of the Force and skills in lightsaber combat. Yoda served as a member of the Jedi High Council in the last centuries of the Galactic Republic and reigned as Grand Master of the Jedi Order before, during and after the devastating Clone Wars. Following the Battle of Geonosis, Yoda held the title of Master of the Order in addition to that of Grand Master. In his centuries of service to the galaxy and the Force, Grand Master Yoda had a hand in the training of nearly all the Jedi in the Order.
Though arguably the Order's greatest master of the Force and most skilled warrior, Yoda believed most firmly in the importance of instructing younger generations and never missed an opportunity to ensure his students learn from their experiences.
The Grand Master was among the few Jedi to survive the Emperor's Great Jedi Purge, after the beginning of which, he went into exile on the swamp planet of Dagobah. The exiled Jedi Master was responsible for the instruction of Luke Skywalker who would use Yoda's training as a basis for the creation of a New Jedi Order.
Can you even imagine living for 900 years? Do you have any thoughts of Yoda?
