If you think about it, Obi-Wan and Yoda also gave themselves over to the Force in a similar fashion, especially since Obi-Wan disappeared an the moment before Vader’s saber hit him.
Did he? I always thought Vader killed him.
yeah he did. vader’s blade never even touches him.
Well I guess that clears up the whole “why didn’t the prequel Jedi disappear when they died?” thing. I guess Yoda and Obi-Wan (and now Luke) gave in to the force.
