Clone Wars was the cartoon series. It had a sequence where the Council debated Anakin's path to Knighthood, and they mention various trials: the Trial of the Flesh and Trial of Spirit were two that I remember; the cartoon series follows Anakin passing that Spirit Trial, and the Council mentions that he already had the Trial of the Flesh at the hands of Dooku (his arm being removed in the process). Oh, and the Trial of Courage.

Facing the Mirror? Sounds like the original Never Ending Story.
I think it's the same as what Luke went through in ESB. Where he went into the cave and such and faced his mirror image nightmare.
Yeah, I just watched the Clone Wars episode...facing the mirror applies to the Test of Spirit. Luke failed his Test of Spirit, needless to say. Not sure about Anakin, though.
