The Spirit is the origin of chi and the behind all bending. Energybending is about manipulating that spirit. I think when Aang removes bending, he's sending a blocking signal to disrupt the spirit's attachment to the elements. But that attachment is likely a two-way street. To be blocked from the elements removes your bending but it could also create a form of natural protection against things like Bloodbending.

I think this last episode gives more credence to the idea that Amon has no bending because it was taken from him by Avatar Aang.

Also, I get the impression that whatever process Amon uses to take bending away, was one he attempted to use on Aang before his death. And I'm guessing that spiritual scar is to blame for Korra's inability to use Air and her difficulties accessing the Avatar state.
