What is Gandalf Talking about?

[inglorion]

The actual text is:

He heard himself crying out: 'Never, never!' Or was it: 'Verily I come, I come to you?' He could not tell. Then as a flash from some other point of power there came to his mind another thought: 'Take it off! Take it off! Fool, take it off! Take of the Ring!'

'Another point of power' seems to refer to some external source of input besides the one Sauron is providing. Gandalf himself says he had some part in the escape of the revealing of the Ring, and I don't think Gandalf is the kind of person who tells you stories about himself that aren't entirely true. Apart from this, the most compelling evidence for proving it was Gandalf, is the fact that the word 'fool' is used. The hobbits, with their naive and care-free behaviours, were extremely good at pushing the boundaries of Gandalf's short and sometimes fierce temper. (F.e. 'Fool of a Took' in Moria)
