Thanks Rian..wonder if that is the entire evidence of this concept?
if so "power with power" is very ambiguous. It would allow Gandalf to attack and destroy any servant of Sauron, and to deceive Sauron. If Sauron were on the other side of a door, could Gandalf hold the door? If Sauron were trying to take over the mind of
Frodo on
Amon Hen, could Gandalf oppose him?
As far as finding things I have found the passage wherein Gandalf takes credit for Amon Hen (Gandalf speaking in TTT,
The White Rider Chapter:
Doesnt this seem inconsistent with the Appendix. Hooray!! another nit.
Let me anticipate the answer: "Well you see, Gandalf was striving with the
Dark Tower, not Sauron himself....Very different...Harrummphh."
