I always used to get confused by it too. I'm guessing you will have already found the answer! But I'll respond anyway (though my interpretation may be slightly different to yours or others).
What was the significance of the hallows? how did they lead him to conquer death? The significance of the Hallows is that they shouldn't be significant; or that's my interpretation. Dumbledore intends Harry to know about them, even to gain the Resurrection stone, but never all three (he had intended to die as the last owner of the Elder Wand, but Draco Malfoy disarmed him). Throughout the series of books, Voldemort is criticised for fearing death by Dumbledore. The irony is that in the 7th book we find that Dumbledore, too, feared death. The significance of the Hallows is I think how 'wrong' they are. I believe that Dumbledore provided Harry with the Resurrection Stone so he would have the courage to face death, but never wanted him to be a master of it.
Why did harry not defending himself mean he did not die? There are many theories. There is a loose explanation at the end of the 7th book, about Voldemort taking in Harry's blood (GoF) and therefore taking Lily's protection upon himself... (see further explanation below). Other theories include that Harry was the master of death, that even though he dropped the ring he had still mastered death, (even Dumbledore saying he was the true owner of the Deathly Hallows, as Harry never wanted to use them for gain). Another is that when Voldemort 'killed' Harry, he only killed the bit of him that was entwined with Voldemort's soul; hence the disgusting baby figure in Harry's hallucination (representing this part of him/Voldemort). This is also why Voldemort was knocked to the ground (see below also). A final conclusion can be that Voldemort attempted to kill Harry with the elder wand... which considered Harry as its Master.
Can someone explain the prophecy, neither can live while the other survives?? because harry lived and voldemort died in the end... I'm confused... you just defined the question? While they're both living however, I think it means that neither can 'live' by any reasonable assumption of the word... more than just a literal meaning.
how did voldemort having harrys blood + lilys protection have any significance (oh and can someone explain what lilys protection is) This I find the most confusing, but I'll try my best. To the latter part of the question, Lily's protection is 'Love'. She died protecting Harry because she loved him, therefore he's protected. The same happens when Harry gives his life for the hundreds fighting for him within Hogwarts... while he did not end up actually giving his life, he intended to, and therefore they were all protected from Voldemort. To the former part of the question, this is because Lily did not die to save Voldemort. This is why the spell rebounds; first when Harry is one, killing Voldemort (though his soul lived on in his horcruxes). The second time it rebounded it destroyed the Horcrux within Harry, and Voldemort also returned (after being knocked down) because Harry had decided to return. If Harry had not decided to return, the same would have happened when Harry was one; Voldemort would have been killed, but his soul would have remained due to the (one) Horcrux that was left. The third and final time Voldemort attempts to kill Harry he no longer has any protection (be it Hallow or Horcrux) and is therefore killed.
- I think it is still down to your own interpretation, but I think that's good! Dumbledore says in the hallucination Kings Cross that even he does not know the answer to everything, but he can guess. This is what we have to do here - it's the mystery of magic! Perhaps JK herself does not even know all the answers :) I hope this helped.
Fell in love with harry potter when i was 5... I saw the first film before i read the books, but that's when the obsession began! My mum and elder sister were going to watch it in the cinema, and I (at the last second), decided I wanted to go too (not knowing either what film we were going to see; nor how dramatically this event would change my life forever). My sister tried to convince me not to go, as I would be 'scared' by the ghosts. How glad I am I ignored that! Over two thirds of my life have henceforth been devoted to this wonderful story.
It was my partner who recently suggested i find a harry potter forum to go on (since i never stop talking about it) and i realised what a great idea that would be. Yes i am as sad as i sound... but it's what I love so who cares?!
