Okay, so the Eye is the "heart", the engine is the engine, the Matrix is the "soul" and artron energy is psychic energy. They all sound important by these analogies.

The only element left from my question is the Time Vortex. Yes, I know that the Time Vortex is what the TARDIS travels through in time and space. But Rose absorbed the Time Vortex from a distinct compartment in the TARDIS and through it was able to do as much destruction as the Meta-Crisis Tenth Doctor! Then, the Ninth Doctor absorbed it from her and put it back into the TARDIS (although it is interesting that this was fatal to him but not to Rose).
