»How did Neo stop sentinals?«

Well your brain emits waves.[http://en.wikipedia.org/wiki/Alpha_waves]
Neo emit so powerful waves that those waves hacked into sentinals ordering them to stop.Or maybe ordered them to get destroyed.

by destroying neo the sententials lost there purpose. (Defense of there machine race) Neo had to reach the source to perpetuate both races. The question is who is destroying the senetinals and how? The path of the one is assisted and hindered by the machine race see all movies. He is constantly tested and helped by programs and machines. The machines sentinals in some way knew him to be the one.
He could see the code written among them the gold code the deep code. Awareness of this code is what allows this to happen

he struggles to defeat a vast majority of them because he has to be constantly aware and completely observant of the code 100% for however long a time... this is more difficult them it sounds

in short the machines allow his entry while testing that he is indeed the one and maintaining to there original programming (whatever that may be) the code is written deep and when he touched the source he saw how to see the code

there is no neo or machines this is the illusion (matrix)...
there is no separation....only one....
you are at best an observer....doing nothing not having anything done to you.

your reaction to reading this is what you are.in this moment.

So, is this place dead?
