Joining the Force
I watched the ESB DVD with commentary yesterday, and Gl made an interesting comment about the Jedi Disappearing trick that many of us have kept occupied for some time now. Why didn't Qui-Gon disappear, did Anakin disappear when he died, how come that we hear Qui-Gon's voice in AOTC, what's this with "when you strike me down I shall become more powerful than you can possibly imagine"? Etc. etc.
Now GL said something interesting about the disappearing trick. He said that it had to do with Jedi 'voluntarily joining the Force" and that it would all be explained in the first three films. I found that interesting becuase I can't really see where that has been explained so far. And volutarily joiing the Force... I've only seen OB1 do that. Qui-Gon was killed, even to his own surprise. Nothing voluntary there. Yoda died of old age ("strong am I with the Force, but not that strong" - he clearly was faced with death he couldn't stop) and Anakin also died of his injuries...
So now I'm even more confused.
