LotR -- Book 2 - Chapter 05 - The Bridge of Khazad-dûm

Gimli took his arm & helped him down to a seat on the step. 'What happened away up there at the door?' he asked. 'Did you meet the beaterof drums?'
'I do not know,' answered Gandalf. 'But I found myself faced by something that I have not met before.I could think of nothing to do but to try & put a shutting spell on the door. I know many; but to do things of that kind rightly takes time, & even then the door can be broken by strength...
Then something came into the chamber- I felt it through the door, & the orcs themselves were afraid & fell silent.It laid hold of the iron ring, & then it percieved me & my spell.
What it was I cannot guess, but I have never felt such a challenge.The counter spell was terrible. It nearly broke me. For an instant the door left my control & began to open.I had to speak a word of Command. That proved too great a strain. The door broke in pieces.'

This is interesting, as it seems to show two kinds of magic at work - spell-casting, & the word of Command. It seems that casting spells is easier than speaking a word of Command. It appears the latter is reserved for extreme circumstances.

Spellcasting appears to work by a kind of 'hypnosis' - not simply hypnosis of people, but a kind of hypnosis of reality itself. Gandalf seems to have 'hypnotised' the door into being locked, by casting a 'spell' - sort of 'telling it a new story' - in the 'old' story it was unlocked (unlockable). Gandalf tells a new 'story', in which it is locked. Then the Balrog comes, & casts a counter spell, tells a new 'story' in which it is not locked. Gandalf & the Balrog contend - as do Finrod & Sauron, & the most powerful magician (ie the 'best', most convincing storyteller) wins out & takes control of 'reality' - from that point the world story carries on, including the changes the storyteller has made.

This is not original, actually - we find this kind of wizardly conflict in The Mabinogion, The Kalevala, The Eddas, etc.

But we also have something different here - the Word of Command. Here we move away from the 'story' that seeks to convince both other minds & the physical matter of Arda to something else, a different kind of power - one that does not attempt to convince but to coerce. Gandalf attempts to Command the world to change rather than persuade it to.

In effect, in the first kind of magic we have the wizard still 'within' the world, trying to convince reality to alter, in the second kind its as if he steps outside the world, & force it to change into something else. Clearly in this case Gandalf is not up to the task, or not used to this way of working, because the door, rather than obeying his Command, simply explodes.

I think this maybe sheds some light on his two confrontations with Saruman - both begin with 'spellcasting' - both wizards attempt to 'persuade' the other into adopting their particular view of 'reality', but then the confrontations move on - in the first it appears it is Saruman who speaks the word of Command - he commands Gandalf to stay in Orthanc - in the second it is Gandalf who speaks the word of Command - Commanding Saruman to return to the balcony & commanding his staff to break.

Too rushed - but perhaps others can add somethinb to this idea - or pull it appart!
